The autocomplete module listens to keypress events for both printable keys
and non-printable keys a lot. However, we're stopping dispatching keypress
events for non-printable keys in the default event group of web content.
This means that autocomplete should listen to keypress events in the
system event group.
Note that it's difficult to globally change keypress event listeners to
keydown event listeners because if we stop keypress events at preceding
keydown event in autocomplete or satchel modules, some other modules
fail to handle keydown or keypress events before autocomplete, and it's
not easy to investigate which keypress event listener in which modules
should be changed to a keydown event listener.
Therefore, this patch doesn't do that, and uses the event group approach.
Even if `<datalist>` is dynamically changed, the autocomplete controller still
uses the previous search result. If changed, we have to ignore the previous
result that may now be invalid.
Also, even if `<datalist>` is changed, we have to keep the selected index
(See Mozilla Bug 595069), so we cannot use `ResetInternalState` in this
situation because it resets the selected index.
This resolves#1509.
Since these are just interpreted comments, there's 0 impact on actual code.
This removes all lines that match /* vim: set(.*)tw=80: */ with S&R -- there are
a few others scattered around which will be removed manually in a second part.
