Hello! I did that already when it was suggested before I made my post.
To clarify: follow the steps I provided. Instead of past steps being properly undone, their text is added onto one another or a new line is added. So,
Text A (delete) Text B (delete)
click back side and hit undo button. turns into:
Text B
Text A
instead of properly stepping back to Text B

A new field, almost like a new window. I’m not surprised it’s so hard to undo. If I enter 111 222, then press DEL, then 111, then 222, and move on to the next field, the 111 will never be restored.

Type some text

Select some text superscript or subscript

If you click the "HTML Editor" button after superscripting or subscripting some text

Then back

If you try to undo with Ctrl+Z again at this point, something strange will happen
Sometimes the undo will fail, sometimes the text will not be undone properly, but the previously deleted text will reappear.
I recorded a video to show it.
After returning from the "HTML Editor", the first time I pressed Ctrl+Z the text did not change (normally, the 12<sup>34567</sup>89 should be 123456789), and when I pressed Ctrl+Z a second time, the previously deleted 999999 appeared. The third time I pressed Ctrl+Z, the 999999 that had suddenly appeared disappeared.

Currently certain operations do not undo correctly, or clear the undo history.
