DeModal + TradeSkillmaster (TSM) opens TSM and Blizz Vendor Window at once

[Shiyoda]

If you open a vendor window while having TSM vendor window active. The Blizz UI Vendor Window will be shown at the top right corner. So you have always both of them open. You can only hide the TSM window.

It worked with 10.0.0 maybe 10.0.2 but definitely not with 10.0.5

This is still a problem with TSM 4.14 and WoW 11.0.5. This addon needs some sort of exception to exclude TSM windows.
