Description Viacheslav Moskalenko 2020-03-09 15:03:33 PDT

Created attachment 393078 [details]
Demonstrating the issue in Safari

Details:
* an input field has some value (say "initial value")
* a user clicks somewhere in the middle of the input field (say, right after "l")
* the input field's value is getting updated programmatically with the same value after n seconds

Expected:
The user's selection (cursor position) doesn't change.

Actual:
A cursor jumps to the end of the input's value (right after "e").

Demo:

Notes:
The cursor positions is correctly handled in:
* Chrome [80.0.3987.132 (Official Build) (64-bit), macOS 10.15.3 (19D76)]
* Firefox [73.0.1 (64-bit), macOS 10.15.3 (19D76)]

I am not able to reproduce the jump issue in Safari 16.2 and Safari Technology Preview 160 but the field does not get focus like Chrome Canary 110 and Firefox Nightly 110 while showing the caret at "iIn" (I as Caret) position, which might be separate issue.

Can someone else confirm and we mark this bug appropriately while using this test case for other bug tracking purpose? Thanks!

Doesn't reproduce anymore.
