Render of fullscreen stopped working correctly with auto hidden taskbar on windows

Issue Type: Bug

Updated VS Code fails to render / restore fullscreen (F11) the first time I run it. It maximizes correctly only after I switch to other window and back to the VS Code window. It’s really annoying.

Here is a screenshot when I run VS Code the first time (black color is my background):

This is a bug in Electron: https://github.com/electron/electron/issues/36638

@deepak1556 leaving it up to you if you want to keep this issue open for reference

//cc @sbatten fyi in this case the workbench believes we are in fullscreen mode and thus the title menu does not render. I am not sure we can workaround that because the window seems to actually then go into fullscreen as soon as you just switch to another app and back

Steps to repro:

• Change OS settings to hide taskbar (alignment does not matter)
• Open VSCode with new user data dir
• Add the following settings

"window.newWindowDimensions": "fullscreen",
"window.restoreFullscreen": true,

• Enter fullscreen and quit VSCode
• Open again with same user data dir and see the issue mentioned in the screenshots above.

Issue happens with both custom and native titlebar.
