Deleting bullets pushes cursor to edge and text vanishes

Using beta 1196662 64 bit on Windows 10 pro 64 bit.

See linked unlisted video.

This bug is specific to case where user has created a list, then tabbed each item to make them sub-items. Here I had it with no items at base indent level at all. (The bug is different if I create a base level list and indent the whole thing in once, and not demonstrated here).

I open a saved project with a previously created list. After opening it, I hit enter to create a new list item.

I then hit delete to remove the list item. Or perhaps instead I hit tab to indent the list item once.

In either case, the cursor moves to the far right and each attempt to write a new character instead creates a new line, cursor still stuck on the right.

If I’m smart and use the keyboard shortcuts to change indent, I can bypass this issue.

Please let me know if you need further clarification.

I’d want to see that with (a) show invisibles activated and (b) the Ruler visible.
