When the mouse is pressed, the mouse event is sent to the currently
focused view. If the view determines the mouse event happened outside of
it (which is the case for what you've been reporting), then the view
discards the event, and Lua gets a chance to handle it (which it does, by
focusing the view clicked on). Subsequent mouse events are then sent to
the newly focused view, and scrolls and selections will occur normally.

In order to match GUI behavior completely, Textadept's C core must
determine where the click occurred and focus the proper view (if
necessary) before sending the mouse click to the view. This duplicates the
Lua mouse handling code already in place, so I'm not sure how I feel about
it. (The Lua mouse handling is based on your code and is required for
split view dragging at least.)

Do you have any thoughts on this?
