This issue is not limited to the end of the address bar. When I keep backspace pressed to delete an overflown URL, the caret will disappear at the left side, and after releasing my finger, some text from the front will re-appear.

This should be fixed in the next Nightly by the work from bug 1994013 and related.

I confirmed that the bug has been fixed on Nightly. It was still broken on a Nightly from a few days ago, and fixed on today's Nightly.

146.0a1 (Build #2016123015), ebd252259b1b0cb286e12edc2e14b9f483444920
GV: 146.0a1-20251028215909

To test, I tried typing lots of text, keeping backspace pressed and pasted a URL that did not fit in the location bar. Before the fix there was an obvious lag in handling/processing, with the fix the caret is at the expected positions.
