Tor Browser on mac momentarily shows two dock icons
When you open TorBrowser.app, for a split-second there are two Tor Browser icons visible in the dock. The first one disappears quickly, leaving just one.
I suppose that the first icon that disappears belongs to the top-level TorBrowser.app; i.e., the one that starts the Contents/MacOS/TorBrowserBundle shell script. The second icon belongs to the inner Contents/MacOS/TorBrowser.app; i.e. Firefox.
I tried adding
<key>LSUIElement</key>
<true/>
to Contents/Info.plist, but it didn't prevent it first icon from appearing momentarily. Setting LSUIElement works when you do it in the inner Contents/MacOS/TorBrowser.app/Contents/Info.plist, so I'm not sure why it works here.
This issue is completely separate from #11429 (moved). These two issues together means that there are actually three icons that are shown at different parts of startup when you configure meek.
