Either on Safari or Chrome for iOS it won't lock the screen orientation, is there any way around this? On Android it appears chrome obeys the orientation lock.
From my experience, In preview mode, orientation lock doesn't work, not until you export it.

I asked about this the other day and Ashley summed it up nicely in this post...
I wonder if I could check the orientation and pause the game with an overlay asking to tilt it back before resuming.
I'll try it later and post back here if its possible...
