Cannot use tab as the trigger character for "format on type"

[datho7561]

Does this issue occur when all extensions are disabled?: No

(You need to have an extension that provides on type formatting with "Tab" as the trigger character)

• VS Code Version: 1.99.3
  17baf84
  x64
• OS Version: Fedora Linux 41
  Linux 6.13.12
  GNOME 47.5

Steps to Reproduce:

1. Install or launch the following minimal reproducing extension: https://github.com/datho7561/vscode-tab-formatting
2. Create a file file.foo.
3. Enable on type formatting
4. Add "lorem ipsum"
5. Hit "Enter". The file should read "alorem ipsum" followed by a newline
6. Set the document indentation to tabs
7. Hit "Tab"
8. The document should read "aalorem ipsum" followed by a newline and tab. Instead, it reads "alorem ipsum" followed by a newline and tab.
