0007372: Missing resize of mixer strip when pin connections change
Description
When changing the pin connections in the mixer strip to some pin connection which needs less space (e.g. from "16" to "automatic" which connects only the first two audio outputs) then then mix strip width isn't shrinked accordingly. When I change from "automatic" to "16" then the width is adapted (in this case expanded) correctly.
See the screenshots for what I mean:
- in 16_out.png the strip has the correct width
- in 2_out.png the strip has the same width as in 16_out.png but actually could/should be more narrow
