[opensource-dev] 'Close' button doesn't work after setting Custom port in Preferences > Setup > Network

[Opensource Obscure]

 I just filed https://jira.secondlife.com/browse/VWR-23993

 Got notice of it on Linux; a friend just confirmed it on Windows.

 I'd think this bug is recent, as in a few weeks. Before then,
 I was using the 'Custom Port' feature with no problems. Then I
 temporarily replaced my router, stopped using the feature,
 and only got aware of it today when I enabled it on a fresh
 viewer install.
 Anyway, I could see it on various releases: 2.3 (official),
 2.4 (mesh), 2.5 (snowstorm).

 The 'Custom Port' option itself seems to work: even if you
 shut down the viewer, your setting sticks when you restart it.
 Problem is you can't close the floater and the Preferences window.
