Edge Dev hanging on open

[cjahn50]

Is anyone else having issues with Edge Dev hanging/not responding on opening? I just updated to 

Version 101.0.1210.2 (Official build) dev (64-bit) but the hanging on open started a rev back.  It seems to occur when Edge restarts after an update and randomly after that.

Here's another 'oddity'. If Edge Dev is minimized for a period of time, say during a sleep period, when it is opened, the tabs that were opened are invisible. The bar is solid black except for the new tab +. Once a new tab is opened all the other tabs reappear.

Looks like that last couple of versions have truly earned the name Dev.

The invisible tab bar is a known issue that we're working on. It happens when a tab updates its title while the window is minimized, and anything that causes the tab bar to repaint (like opening a new tab) will fix it.
