javascript - How did the popup of this chrome extension open from bottom? -
i know chrome extensions , built one.
as far know, popup can opened button action (page action too) , closed once lose focus (i.e. if users clicks somewhere on webpage).
but how did extension - barc manage
1) open bottom
2) refrain closing after losing focus
i looked @ chrome://flags/#enable-panels
, found panels disabled. so, ain't cause.
i'll happy if 1 can point me underpinnings of implementation or api?
it's injecting custom ui pages via content scripts, not showing in panel.
you can test minimizing/moving chrome window.
