Unexpected behavior in splitting cells in certain tables

[mabryl]

📝 Provide detailed reproduction steps (if any)

1. Pass the HTML attached to this issue to create a table with a certain layout or create one from scratch that resembles the one that you can see in the recording in Actual result
2. Try splitting the cell on the left side

✔️ Expected result

The cell should probably split in two, as is the case in CKE4:

cke4_split.mov

❌ Actual result

The cell splits into multiple ones. The structure of the table is further altered and an additional column gets inserted on the right:

cke5_split.mov

❓ Possible solution

It might have something to do with the number of cells to the right of the cell that is being split. The smallest possible table configuration that reproduces this issue needs 7 rows and two columns. Notice that the issue doesn't appear when there are 6 rows:

6_7_rows_split.mov

📃 Other details

• Browser: cross-browser

Probably some rounding issue.
