Website environment disappears suddenly

After I updated to visionOS 26.4, I noticed my website environment would suddenly turn off occasionally while I was watching YouTube in Safari.

My M2 AVP was still warm after the update.

Is turning off a website environment expected behavior when the headset gets warm (e.g., perhaps to reduce load)?

If not, anyone have an idea this might happen?
