What it does

Fixes #7232

This commit reverts the breaking change of #7216 which meant that users would not be able to provide keyboard input any longer in a webview.

How to test

1. use any webview which can require user input
   1.1 for my test I used gitlens (also added builtin-git, builtin-git-ui and removed @theia/git)
   1.2 opened the Gitlens: Welcome which required input
2. input should now be accepted by users

@akosyakov maybe it would be better in future just to prevent reserved browser hotkeys, like CtrlCmd+P, CtrlCmd+O, F1, etc. WDYT?

[akosyakov]

@vzhukovskii Please file a Theia issue for your original issue, we could think how we can tackle it if we can at all. I would assume that webview has a priority and can install handlers for f1 as well. Also looking at the code we don't prevent any webviews actions. Could it be that your webview installing a handler which prevents an event propagation to the main window?

@akosyakov here is the issue for that #7235
