Fix by always testing unhandled double-click events as press events,
irrespective of the previous event type.
**Details**
Handling double-click events only ran when the previously pressed-key
matched the current pressed-key.
Originally when double-click support was added the previous type was
compared (ignoring it's press/release value) and while not necessary
it was harmless as it matched the check for double-click events being
generated.
As of [0] the logic for click/drag detection changed to ignore release
events as release this could interrupt dragging.
This made it possible to generate double-click events that failed the
`event->prev_press_type == event->type` comparison.
In these cases it was possible to generate double-click
events that would not fall-back to a 'press' value when unhandled.
