Tiles from MVT cannot be displayed.

[delicadiesel]

What steps will reproduce the problem?

1. I click +MVT in the Imagery preferences.
2. I add MVT URL mvt:https://demotiles.maplibre.org/style.json
3. I expect this MVT Imagery will be displayed just like the map on ​https://maplibre.org/
4. But, I get an error below.
5. Could you please include the Maplibre rendering engine from ​https://maplibre.org/
