Issue while Dock and UnDock quickly for main window: Tab Lost , as it is neither on Docking view nor on the main view

[HT2207]

I am using your library with Nuget package since a year and it is perfect for my requirement
But I found out that if I do Docking and Undocking quickly, it lost the Tab
I attached video using your Demo

ChromeTabs_Error.mp4

Log lines are

has mouse capture=true
11:42 dragging window
sendt close tab command
11:42 closed window
2)
has mouse capture=true
11:42 dragging window
sendt close tab command
11:42 closed window
3)
has mouse capture=true
11:42 dragging window
sendt close tab command
11:42 closed window
4)
has mouse capture=true
11:42 dragging window
sendt close tab command
11:42 closed window
5)
has mouse capture=true
11:42 dragging window
11:42 closed window
sendt close tab command

For the first (1) to (4) tries docking and undocking works perfectly fine BUT for the last time(5) when Tab Lost, last two log lines says that order of calling close Tab command is reversed compare to earlier tries from (1) to (4)

Please suggest a way to solve it
