Webview copy/paste shortcuts broken in 1.50-insiders

Version: 1.50.0-insider
Commit: f943318
Date: 2020-09-23T05:28:07.760Z (11 hrs ago)
Electron: 9.3.0
Chrome: 83.0.4103.122
Node.js: 12.14.1
V8: 8.3.110.13-electron.0
OS: Darwin x64 18.7.0

Steps to Reproduce:

1. Download the vscode extension samples (https://github.com/microsoft/vscode-extension-samples.git)
2. Modify the html in the cat coding webview sample to have a <input>
3. Run the cat coding webview
4. Type some text into the text area, select it, and try to ctrl+c / ctrl+v

Ctrl+c doesn't write to the clipboard, and ctrl+v has no effect.

This is causing https://github.com/microsoft/vscode-python/issues/14053 in the Python extension. I was on 1.48-insiders right before updating to repro this with our customer's setup, and this bug was not present in that build.

Does this issue occur when all extensions are disabled?: Yes

Thanks for submitting this issue. Please also check if it is already covered by an existing one, like:

• Pasting in webview also pastes into the terminal (#103200)

Do you see it in 1.49 as well?

[mjbvz]

Actually, pretty simple fix. I suspect it's in 1.49 too but not on web (and not with iframe based webviews on desktop)

@mjbvz, do you know when this fix will become available in insiders? I see that this issue is tagged released, but we had another customer report the same issue 4 days ago: https://github.com/microsoft/vscode-python/issues/14095, and I still repro the problem locally. Thanks so much 😊

I just tested using 772aa07 on Mac and Windows and it seems to be fine. Can you verify you are on that build and that copy/paste doesn't work in the sample extension specifically

[joyceerhl]

Ah yes it seems to work fine with the sample extension. Thanks Matt!
