Regression: When having VLC play a twitch stream using 'streamlink', the current stream timestamp in the GUI is incorrect

When streaming a twitch stream using 'streamlink', the current stream time timestamp should be displayed above the pause button, showing how many seconds have elapsed since the stream started, regardless of when streamlink/vlc was launched. This used to work, and works correctly in the nightly build (https://artifacts.videolan.org/vlc-3.0/nightly-win64/20220323-0406/) based on 296b3a03 but regressed and instead shows a time starting at about 0:05 and counting upward based on how long your current streamlink/vlc session was open, starting at the nightly build (https://artifacts.videolan.org/vlc-3.0/nightly-win64/20220325-0225/) based on c7cfe89c

This was tested using the exact same version of streamlink with the same exact settings, with both vlc builds.
