Widget Inspector breaks when its tab is undocked or re-docked. #5116
Description
Description
When I open the Widget Inspector, and then grab the tab and drag it outside of the main window to turn it into a separate floating window, the window goes blank and the inspector no longer works until I reload the entire app. Even then, I have to restart my debug session and turn on the Widget Inspector again before it will show up in the floating window.
The same thing happens if I drag the external tab back into the main window to dock it.
Seems like the Widget Inspector has trouble re-homing itself.
To Reproduce
Steps to reproduce the behavior:
- Open VSCode on a Flutter app (sample app will do)
- Debug the app (I was on Linux debugging a native linux app)
- Click the widget inspector button to show it in a tab next to the editor window.
- Drag the tab outside of the main window to undock the tab.
- Notice that it's blank.
- Do Ctrl-Shift-P and execute the "Developer: Reload Window" action.
- Debug the app again
- Open the widget inspector again.
- Notice that it's working again.
- Drag it back into the main window to dock it.
- Notice that it's blank again.
Expected behavior
I would expect the Widget Inspector to just stay in the tab when I undock and dock it.
