Electron 3.0.0-beta.8 changed the <webview> implementation to "Out of Process Iframe". This issue tracks regressions found by that move.

There is still lots of flakiness in <webview> with regards to focus. It seems that the fact that we use an <iframe> within the <webview> makes proper focus/blur detection harder.

I think the context key in webviewElement.ts should not work with focus/blur but rather just be enabled when the active editor is a <webview> editor. Ideally we do not have to rely on focus/blur at all for the commands (select all, find) to work.

More things to test: use an extension such as negokaz.live-server-preview-0.1.2 that leverages HTMLPreviewPart and check if focus handling works properly. We should also let the MS SQL extension team do a test with Electron 3.0.x because they seem to rely most on the <webview> from all extensions.

I pushed another comment to move away from DOM.trackFocus() for the webview element and rather send an explicit event.

There is still focus issues when doing this:

  • install negokaz.live-server-preview-0.1.2
  • open a empty HTML file and type some words
  • open preview to the side
  • click between editor and right hand preview

=> at one point focus is no longer detected

Another issue (macOS):

  • open one editor (markdown)
  • open preview to the side
  • hit Cmd+W to close
  • => both editors close

It looks like both the Cmd+W is fired from within the webview as well as the File > Close Editor menu entry from the global menu.

I opened electron/electron#14514

Update: it looks like calling webContents.setIgnoreMenuShortcuts(true) (somewhere here) fixes this issue however has one downside: any menu item on macOS that has a role associated (cut, copy, paste for example) needs to be implemented manually in the webview, otherwise we loose that functionality.
