error in select all box for updates

[JKEngineer]

The behavior of the Select All box in the plugin (and theme?) update boxes recently changed.
I have described it in detail here: ​https://wordpress.org/support/topic/error-in-select-all-box-for-updates/#post-17812157
It is demonstrated via loom:

Short version:
In the Update Panel: Selecting any plugin for update causes the Select All box to be checked, even if there are other updates not selected. Unchecking the plugin does not uncheck the Select All box. Manually checking the Select All box does, as expected, select all the updates.

I have seen this happen on several websites, on different hosts. The current WP version on them is 6.5.4, but I have had this happening for a few updates of WP.
