Table resize uses incorrect pointer delta inside a transformed inline editor

Provide detailed reproduction steps (if any)

Please provide the steps to reproduce and if possible a minimal demo of the problem via fiddle.tiny.cloud or similar.

1. Open the link https://fiddle.tiny.cloud/tWW4xfIxKs/2
2. Try scaling table's grid boundaries on the first table - everything works just fine.
3. Try doing the same on the second table where the wrapper is scaled using transform: scale(0.5).

• The actual scaling is halved relative to the cursor delta - moving the cursor by, say, 100px, moves the matching table separator by only 50px.
• The same bug applies to the cursor ew-resize and ns-resize appearance transformation: The cursor appearance is changed at a halved offset from the TinyMCE's top-left position than where it should be: Say the column has a width of 200px, then the cursor is transformed at the document's position of 100px, which is in the TinyMCE's editor position of 200px because it is scaled down by a half.
