The Jetpack Carousel viewer doesn't work after the Wordpress 4.5 update

[edvardtoth]

Following the 4.5 Wordpress update Jetpack Carousel (v3.9.6) is not launched when gallery-images are clicked on (this seems to affect other lightbox-type viewer plugins as well, like WP Featherlight).

Instead, the images go to their corresponding attachment pages.

This page is a good example: ​http://edvardtoth.com/art/personal-gallery/
It also demonstrates other Carousel functionality (caption on rollover) being broken too (the captions are permanently shown, instead of appearing on rollover).

The problematic behavior remains unchanged even when:

• all other plugins are disabled
• other themes are used
• all caches are purged, minify is disabled, etc.

Hi @edvardtoth,

Core Trac is used for tracking bugs in the core software itself. Until the Jetpack team has identified a core bug, your best bet is to post in the ​support forums for Jetpack to see if they've identified any incompatibilities with WordPress 4.5.

In 37879:

Media: Add action to display attachments on the edit screen.

This adds a new action hook, wp_edit_form_attachment_display to
edit_form_image_editor(), which can be used as a fallback to render
previews of an attachment that isn't an image, audio, or video file
included in the media library.

Props georgestephanis.
Fixes #36502.

Gah. Wrong ticket. Intended for #36052.

Gah. Wrong ticket. Attended for #36052.

It's OK, you get another chance :-)

The @param line in the hook doc is missing the variable reference:
