Created attachment 8471627 [details] test case: nolineatoffset.html Steps to reproduce: 1. Load the attached test case in Firefox 2. Load the attached accessible event listener in a terminal 3. Enable caret navigation in Firefox (F7) 4. Arrow left and right within the line to move the caret Expected results: The accessible event listener would print "hello world" and the associated start and end offsets each time the caret moves. Actual results: The accessible event listener prints an empty line each time the caret moves. Sample output: Caret moved in [section | ] to offset 3 Line at offset 3: ('', 0, 0) Caret moved in [section | ] to offset 4 Line at offset 4: ('', 0, 0) Caret moved in [section | ] to offset 5 Line at offset 5: ('', 0, 0)
I can reproduce this too. Note that you can still reproduce it if you remove the div (except that obviously you'll be fetching offsets from the document accessible).
