ctrl+z / ctrl+shift+z (undo/redo) not working for input elements when a custom editor is open

Does this issue occur when all extensions are disabled?: Yes (affects extension authoring)

• VS Code Version: 1.94.0-insider
• OS Version: Mac Sonoma 14.6.1

Steps to Reproduce:

1. Modify webview-view-sample's webview HTML to include an <input> element

2. Compile and package the webview extension (will need to modify the publisher tag), then install it locally

3. Compile and run the custom-editor-sample

4. Open the calico colors webview view

5. Observe that when no custom editors are open, the ctrl+z / ctrl+shift+z events work

6. Open the custom editor

7. Observe that the undo/redo hotkeys no longer work in the webview view
