Because quick commit popup show when click A tag on hovering line popup, vscode do not know what should be focus. So we need hide hovering line popup before show quick commit popup.

@eamodio Hi, could you review it?

Sorry for the delay. I can't reproduce this issue but it must be a VS Code bug of some kind. Since this "fix" is a hack to workaround that bug and that it is forcing focus to something that may or may not have focus, I don't think GitLens should attempt to fix it. Forcing focus to the active editor group, could have implications to keyboard usage and screen reader support.
