[Bug]: backspace with empty list item in safari with software keyboard causing invalid behavior

Affected Packages

core, extension-list-item, extension-list-keymap

Version(s)

2.9.0

Bug Description

This issue occurs when using safari iOS with the standard software keyboard. When you have the cursor at the front of the paragraph of a list item and try to press backspace, it instead removes the list item and moves the paragraph into the list item above as a sibling.

This is a video testing on TipTap's own website for list-keymap which should combine the two bullets into one on the first backspace click:

list.backspace.ios.software.keyboard.mp4

After further investigation, it appears that something is intercepting the backspace command and setting preventDefault to true before the event even gets to TipTap.

This is happening on iOS 17.5 and iOS 18 via the simulator.

Weirdly enough, the intended behavior occurs when I open the site on iOS 18.1 on safari with software keyboard.

Expected Behavior
