Adjust attach syntax for Backdrop.

[Wylbur]

I have the RC3 version of the module installed.
Editing a node with a body field.
Using CKEditor5, and trying to insert a image via the media module.

The media overlay never appears, I just get a small overlay with the word "Loading".

Here's the error message from the console

description_toggle.js?v=1.32.1:4

Uncaught TypeError: context.querySelectorAll is not a function

Switching to the Seven admin theme resolves the issue for me.

@Wylbur Can you try turning off the "Hide descriptions" option in Gin and see if it changes things? The error looks like it may be related to that setting.

[Wylbur]

@laryn YES, disabling the "Enable form description toggle" does resolve the issue with using media in the CKEditor window!

This has no effect on the dark/light/auto mode.

@Wylbur I pushed a commit but would still love if you could verify it works for you. It looks like I let slip through a syntax change during a pull from the Drupal upstream:

This is in the latest release -- if verified by @Wylbur we can close this issue.

Using the lastest release, I cannot reproduce this issue.

I got that dialog box clicking on the highlighted icon in the following screenshot, which was one of the icons shown by CkEdit 5 for a Body field. (In my case, it was for a Post node.)

[laryn]

Thanks @avpaderno! If you continue to see an issue with the latest release, please reopen, @Wylbur.

WOW, this works, but it took some work on my part to get it working. I cleared caches, and switched themes, but it was still not working.

What DID work was to set admin theme as Seven, disable GIN, then enable, then set as admin theme.

Great work @laryn and @avpaderno

@laryn even with commit 1047d69 enabling "Enable form description toggle" breaks the JS.
