Description

I found a case where I'm trying to insert a character after the last character in a group, and moves to after the first character after the group.

Please find screen recordings of the issue:

Steps to Reproduce

1. Type in any LaTeX group. Then, Type any series of characters or commands after it. For example: {123}abc
2. Move to the character before the last character in the group
3. Try to move forward using the keyboard arrows.

Actual Behavior

It moves to the 2nd element after the group

Expected Behavior

It should move to the last element in the group.

I'm not sure if this is a new issue, or it were in previous versions also.
