Table resize after column insert undo crashes the editor

[Acrophost]

📝 Provide detailed reproduction steps (if any)

1. Insert a table
2. Insert a new column somewhere in the middle of created table
3. Change the width of new column with column resize
4. Undo to the point before adding new column
5. Attempt to resize the table with rightmost column resize

✔️ Expected result

Table will properly resize without any jumps.

❌ Actual result

Column resize doesn't budge no matter how much force is used on it.
Console throws a wall of errors.
The editor is now working in an extremely bugged way.

📃 Other details

Console error:

Uncaught TypeError: Cannot read properties of undefined (reading '\_setStyle')

If in step 5 a different resize is used, the columns jump a bit and table resizes in a bugged way.
After that everything works as expected.
