Did a quick test on the new BG image feature and it seems to only display at 500px height.
Added a section, then dragged the BG video element into it. Section was set to 100% height, 100VH, 800px, a whole bunch of stuff, yet the video always displayed at 500px.
Is this by design? There appears to be no setting for this feature other than the upload button.
Thanks for any advice!
