I can confirm this issue is still not fixed in v2.4, and it's also present in PTC v2.5.
This appears to be a system-level issue.
If you go to OS Recording settings (Camera settings) and change the recording reference point from Left (default) to Right, then restart and view a 180° 3D SBS video in the browser, the video now only displays in the right eye instead. The left eye shows black, or more accurately, the video appears to be rendering behind the user - similar to how a 360 video would render incorrectly.
Update: I checked again today and something changed. Even if I change the Camera/Recording reference setting from Left to Right now, the eye that doesn't display the video is fixed to the right side. It still plays behind the user, just like before.
I checked the system settings and the install date shows June 3rd, so it looks like the headset updated overnight while I was asleep...
The issue is still there, but the behavior with the recording setting seems to have changed slightly with this update.
