A race condition has caused the wrong input element to be set as the
active, focused one when a script on a website reacts to autocomplete
inputs and manipulates the inputs. This happened because the
FormFillController listens for changes to the attributes of the input
elements, and then restarts itself delayed. This overwrote the focus
that had been set correctly in the meantime. This patch cancels this
restart when a new element is set as focus.

I've replicated this issue using Nightly 118.0a1 on Windows 10 x64.
Verified as fixed in the latest Nightly 128.0a1 version on Windows 10 x64, macOS 11, and Ubuntu 22.04, as the issue no longer occurs.
