VLC 4.0.0-dev can't display some avif images

Using one of the examples by netflix here http://download.opencontent.netflix.com/?prefix=AV1/Chimera/AVIF/, eg http://download.opencontent.netflix.com.s3.amazonaws.com/AV1/Chimera/AVIF/Chimera-AV1-8bit-480x270-552kbps-100.avif VLC doesn't display anything.

The ones from Microsoft available here https://github.com/AOMediaCodec/av1-avif/tree/master/testFiles/Microsoft do work on the other hand

Using the nightly build from tonight for 4.0.0-dev on OS X.
