  /**
   * Mixin for input views handling common concerns like labels,
   * inline help, visiblity and disabling.
   *
   * ## Label and Inline Help Translations
   *
   * By default `#labelText` and `#inlineHelpText` are defined through
   * translations. If no `attributeTranslationKeyPrefixes` are given,
   * translation keys for labels and inline help are constructed from
   * the `i18nKey` of the model and the given `propertyName`
   * option. Suppose the model's `i18nKey` is "page" and the
   * `propertyName` option is "title". Then the key
   *
   *     activerecord.attributes.page.title
   *
   * will be used for the label. And the key
   *
   *     pageflow.ui.inline_help.page.title_html
   *     pageflow.ui.inline_help.page.title
   *
   * will be used for the inline help.
   *
   * ### Attribute Translation Key Prefixes
   *
   * The `attributeTranslationKeyPrefixes` option can be used to supply
   * an array of scopes in which label and inline help translations
   * shall be looked up based on the `propertyName` option.
   *
   * Suppose the array `['some.attributes', 'fallback.attributes']` is
   * given as `attributeTranslationKeyPrefixes` option. Then, in the
   * example above, the first existing translation key is used as label:
   *
   *     some.attributes.title.label
   *     fallback.attributes.title.label
   *     activerecord.attributes.post.title
   *
   * Accordingly, for the inline help:
   *
   *     some.attributes.title.inline_help_html
   *     some.attributes.title.inline_help
   *     fallback.attributes.title.inline_help_html
   *     fallback.attributes.title.inline_help
   *     pageflow.ui.inline_help.post.title_html
   *     pageflow.ui.inline_help.post.title
   *
   * This setup allows to keep all translation keys for an attribute
   * to share a common prefix:
   *
   *     some:
   *       attributes:
   *         title:
   *           label: "Label"
   *           inline_help: "..."
   *           inline_help_disabled: "..."
   *
   * ### Inline Help for Disabled Inputs
   *
   * For each inline help translation key, a separate key with an
   * `"_disabled"` suffix can be supplied, which provides a help string
   * that shall be displayed when the input is disabled. More specific
   * attribute translation key prefixes take precedence over suffixed
   * keys:
   *
   *     some.attributes.title.inline_help_html
   *     some.attributes.title.inline_help
   *     some.attributes.title.inline_help_disabled_html
   *     some.attributes.title.inline_help_disabled
   *     fallback.attributes.title.inline_help_html
   *     fallback.attributes.title.inline_help
   *     fallback.attributes.title.inline_help_disabled_html
   *     fallback.attributes.title.inline_help_disabled
   *     pageflow.ui.inline_help.post.title_html
   *     pageflow.ui.inline_help.post.title
   *     pageflow.ui.inline_help.post.title_disabled_html
   *     pageflow.ui.inline_help.post.title_disabled
   *
   * @param {string} options
   *   Common constructor options for all views that include this mixin.
   *
   * @param {string} options.propertyName
   *   Name of the attribute on the model to display and edit.
   *
   * @param {string} [options.label]
   *   Label text for the input.
   *
   * @param {string[]} [options.attributeTranslationKeyPrefixes]
   *   An array of prefixes to lookup translations for labels and
   *   inline help texts based on attribute names.
   *
   * @param {string} [options.additionalInlineHelpText]
   *   A text that will be appended to the translation based inline
   *   text.
   *
   * @param {boolean} [options.disabled]
   *   Render input as disabled.
   *
   * @param {string} [options.visibleBinding]
   *   Name of an attribute to control whether the input is visible. If
   *   the `visible` and `visibleBindingValue` options are not set,
   *   input will be visible whenever this attribute has a truthy value.
   *
   * @param {function|boolean} [options.visible]
   *   A Function taking the value of the `visibleBinding` attribute as
   *   parameter. Input will be visible only if function returns `true`.
   *
   * @param {any} [options.visibleBindingValue]
   *   Input will be visible whenever the value of the `visibleBinding`
   *   attribute equals the value of this option.
