Unable to remove mark after deleting marked characters (cursor-only state) - v0.0.13-alpha.3

[arisgk]

Description

When using v0.0.13-alpha.3 I'm encountering a problem when trying to unmark text after deleting marked characters, with no text selected (i.e., in a cursor-only state).

The recording below demonstrates the issue in the playground:

unmark-cursor-issue.mp4

How to Reproduce

1. Type some plain text
2. With the cursor at the end of the text, apply a mark (e.g. bold)
3. Type some marked characters
4. Delete all the marked characters
5. Remove the mark
6. Type some more characters

Expected behavior

The characters typed in step 6 must be unmarked (plain text).

Actual behavior

The characters typed in step 6 are still marked (unmarking wasn't applied properly).

Looked briefly into this; might be the same issue mentioned in #2 or #3.
