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

• VS Code Version: 1.91.0
• OS Version: Windows 10 10.0.19045 Build 19045

Steps to Reproduce:

1. Have outgoing changes in your source control view.
2. Click on a file that has changes in a commit to open diff view.
3. Configure a shortcut for the Open File action.
4. Press the shortcut.
5. Observe that the file is opened in read only mode.
6. Go back to the diff view and click the Open File button with a mouse.
7. Observe that the file opened in writeable mode.

Expected results:

1. The way the action is invoked should not affect the mode in which the file is opened. I would personally prefer it to always open file in writeable mode if possible.
