Javascript Crashes when loading existing Tags in a Post

    Hi,
    We have a problem on a website with a lot of Terms in the post_tag Taxonomy.
    We have recently upgraded WordPress from 5.4.2 to 5.8 and since the upgrade, the browser tab crashes whenever I write something in the tag input field.

    The ajax call (/wp-admin/admin-ajax.php?action=ajax-tag-search&tax=post_tag&q=texthere) is executed correctly and in a timely manner.
    The problem is evidently the javascript handling the creation of the list of matching tags.

    I still have a testing server with 5.4.2 installed and I can confirm that it handles the same number of results without any issue.

    Does anyone have a solution for this?
    Thank you!

    This may be a plugin or theme conflict. Please attempt to disable all plugins, and switch to the default Twenty Twenty-One theme. If the problem goes away, enable them one by one to identify the source of the problem.

    If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site.

    Hi James,
    thank you for the advice, I was able to pin point the issue.

    It only occurs while using the classic editor, so the problem must be in the classic editor plugin javascript that constructs the list of tags.
    I can also confirm that in previous versions it works just fine.

    The users that write the posts use the classic editor and already tried to kill me when I suggested they use the block editor, so I really need a fix for this.

    Thank you!

    Let me update on this.
    After trying with earlier versions of the plugin with no changes, I started downgrading WordPress and found out that Everything works fine up until version 5.5.5 and it breaks when I use version 5.6.

    I hope this helps.

    Please attempt to disable all plugins except Classic Editor, and switch to the default Twenty Twenty-One theme. If the problem goes away, enable them one by one to identify the source of the problem.

    Ok, then since the problem only happens when the Classic Editor plugin is active, I recommend reporting the issue at https://ww.wp.xz.cn/support/plugin/classic-editor/ so the plugin’s developers and support community can help you with this.
