Featured Image on Page dialog does not show alt value from DAM

[HitmanInWis]

Bug present as of version: 2.24.7-SNAPSHOT

When loading a Page Properties dialog where the featured image is set, the Alt text from the DAM does not show in the "Alternative Text" box. NOTE: This bug does not happen on first set of the image (alt value is displayed correctly) - only upon opening the page properties dialog again after setting the image and saving.

This can be resolved by setting the altTextFromDAM property on initialization of JS code in image.js

Update the following code:

            altTextFromPage = $dialogContent.find(pageImageThumbnailImageSelector).attr("alt");

to:

            if (isPageDialog) {
                altTextFromDAM = $dialogContent.find('coral-fileupload[name="./cq:featuredimage/file"] img').attr("alt");
            } else {
                altTextFromPage = $dialogContent.find(pageImageThumbnailImageSelector).attr("alt");
            }

The isPageDialog var is effectively $(pageAltCheckboxSelector).length === 1 which is higher up in the initialization code.
