Word Count on Classic Editor doesn't update in real time on Firefox unless saved

[rebasaurus]

This has been happening on 5.6 using Firefox 83.0. I was unable to reproduce on 5.5.1.

To reproduce on 5.6:

1) Install the Classic Editor plugin and enable it
2) Type out a bunch of words on a new post and see that "Word count: 0" remains
3) Save as draft and see that "Word count: x" has updated

Also, I just wanted to mention that it's not reproducible using Chrome — just FF. Using the jquery migrate helper plugin does resolve the issue.

Hello @rebasaurus,

Welcome to WordPress Core Trac! Thank you for the ticket.

With WP 5.6:

• I was able to reproduce the problem in Firefox v84.0.1.
• It worked as expected in Chrome Version 87.0.4280.88 and Safari Version 14.0.2.

With 5.5.3:

• It worked as expected in Firefox, Chrome, and Safari.

My local testing environment:

• Theme: Twenty Twenty-One
• Plugins: only the Classic Editor plugin
• PHP: 7.3.5
• Classic Editor: 1.6

Moving this ticket into 5.6.1.

Looks like https://core.trac.wordpress.org/ticket/52046 is related and there was a changeset pushed to it recently.

Yes @rebasaurus. I can confirm that. I'm not able to reproduce the issue on the latest version of trunk.

Re-testing in Firefox version 84.0.2. Works!

Checkout out the current 5.6.1 branch. I too can confirm that it now works (see attached gif).

@rebasaurus is the issue resolved for you too?

[hellofromTonya]

Marking this ticket as a close candidate pending reporter feedback as we're unable to reproduce the reported problem with the latest 5.6.1 branch.

[rebasaurus]

Thanks @hellofromTonya. I've just tested the latest nightly build and it appears to no longer be an issue. I think we can close this now.

[hellofromTonya]

Closing as "fixed" as it was fixed in core since being first reported.
