[3.2.6] Adding Categories not firing Preview update

[narration-sd]

Description

I just noticed this testing Live Vue Gatsby samples for release, so it feels recent. Other types like images, texts Redactor or simple, etc. are fine, but when I add a category to an Entry's list, by selecting from the usual hud, there's no preview update -- until I mouse in one of the text fields. That's all it takes.

There might be a delay, even then, compared to other edits -- not certain but should be checked.

Removing a category, on the other hand, immediately updates fine.

Steps to reproduce

1. EntryType with a category Field
2. Edit an Entry with it, fresh new or otherwise - I checked both
3. Use the Add a Category button, and select one available
4. Nothing happens
5. Now mouse within a text or Redactor field of the CP Editor
6. Previewed category list updates, maybe with a delay
7. Stabilize, then remove a category on the edit side
8. Proper immediate update happens, and preview shows the removed gone

Thanks! All fixed for the next release.

Hmm. This seems not to do the trick yet....

• tested on your hash plus current dev-master
• tested on current Chrome, Firefox, and the Chrome Canary I usually use
• all testing on Win10 latest and greatest (?...)

On each of these, same behavior as before in issue, no updates until mousing in a text field afterwards

Your craftcms/cms requirement should be set to dev-develop#b6836a8412bcf775196e14d1c3bf815ef4a2c9b4, not dev-master#....

I did that first -- and still. The dev-master plain thing was just to see if there was a difference.

Also lots of clear browser cache total/restart, vagrant reload, etc. to try to eliminate caches.

It looks pretty solid...?

        "craftcms/cms": "dev-develop#b6836a8412bcf775196e14d1c3bf815ef4a2c9b4 as 3.2.5",

Doh sorry, I forgot that Categories fields don't call selectElements() like other relational fields. Really fixed now. Use dev-develop#6f47e6aa8a988639152619a462f2082bea675d1d.

[narration-sd]

will try :)

Bingo -- works fine, multiple cat adds included.

And now no delays, either...

Cheers, @brandonkelly
