display position subscriber isn't notified of stream position change on chat panel resize

[gostay]

In a browser window on a stream channel with custom controls, when the chat window is resized, the stream's position changes, but subscribers to display.position() are not notified of that change, so our custom controls stay in the old position.

I get a window resize event when the chat is resized, but I don't get a mixer display position handler update. Shouldn't I?

(When the whole browser window is resized, I do get mixer display position handler updates.)
