Ctrl-S is now Browser-Save instead of Workflow-Save

When you hit Ctrl-S in a Workflow in ComfyUI, then this used to work as "save workflow".
This is now apparently intercepted by the Browser (Firefox 153.0.4 on Linux Mint 22.3 in my case), so I get a browser save-dialog to save the page as .hml
From the main Menu, you can still select "File" and then "Save", which works correctly.
And from the Workflow Actions menu, the Save there also still works.
But Ctrl-S no longer behaves as before (i.e. Save Workflow).
(other keyboard shortcuts like Ctrl-O, Ctrl-A, ... all still work correctly)

Reproduce the issue in Firefox on Linux and compare Ctrl-S with File > Save and Workflow Actions > Save, which still work. Trace the frontend keyboard-shortcut handling for Ctrl-S and verify that the browser save dialog no longer appears and the workflow is saved through the existing action.
