if i launch epiphany-browser from the show applications menu layout it opens only one window, as in one instance of the browser just like it should.
but if i launch epiphany-browser from the dock it opens two windows, as in two instances of the browser.
this occurs only with epiphany-browser & none of the other items in the dock.
did a fresh install of 20.04 to confirm the bug & i can surely concur that when launched from the dock epiphany-browser open 2 windows every time instead of one.
this should give you a better idea of the bug :
can any else confirm if they face the same problem ?
