The current behavior

There is an issue where deleting with backspace when BlockWithAlignableContents is contiguous deletes the previous node along with it.

The expected behavior

Only the selected nodes should be deleted.

@ssoju - Which browser are you using? I tried on Chrome Version 119.0.6045.160 (Official Build) (64-bit) and Firefox Version 120.0 (64-bit) both on Windows 11. It seems to work fine on my end.

@disalechinmay My chrome is "119.0.6045.159". It also happens on Canary, which is "121.0.6144.0". Firefox is "120.0".
If you watch the video, it still happens.
