[5.x]: Nested matrix entry types disappear when page is reloaded after making changes

sparkalow commented 3 months ago

What happened?

Description

When editing fields of a nested entry in a matrix field, the "changed" fields blue indicators show as expected. However, reloading the page results in the changed blocks disappearing. This only seems to happen with blocks set to "inline editable" display mode. Saving in this state will result in the blocks being deleted. Discarding changes will restore the missing bits.

Steps to reproduce

Edit an entry that has a matrix field that contains a nested matrix field with multiple entries - set to display "inline editable blocks."
Edit at least 2 of the nested matrix entries.
Reload the page.

Expected behavior

All edits are shown in "draft" mode with changes hi-lighted.

Actual behavior

The changed nested entries no longer show and appear to have been deleted.

I've created a vanilla install with no plugins that can reproduce this consistently and can provide a db dump.
