Fix Live Markdown Input undo/redo history on web

Skalakid commented 2 months ago

This PR enhances undo/redo history logic. The main changes are:

changed the debouncedAdd function to throttledAdd. Now it instantly adds an item to history and until the throttle time ends, executing it again will only modify the previously added item. After the time ends, launching throttledAdd will add a new element. Before these changes debouncedAdd function was adding an element to history after the debounce time
fixed cursor positioning when undoing text. Now cursor is positioned at the beginning of the text that was undone

Copy and paste text into Live Markdown Input somewhere else than the end of the value inside
Try to undo it immediately after pasting it
Verify if text was undone and if cursor position was set it the place where the undo text was beginning

One small bug - cursor position is incorrect here after undo
