I don't know what's the cause, but using the Coder on Coder template on dev.coder.com, I'm seeing metadata appears for a short while, only to disappear again. This happens repeatedly.

Meanwhile, the VSCode extension is showing the values correctly.

Video:

Metadata appear at 0:58 and 3:58, so it seems to be on some interval. There might've been a redeploy/reconnect of dev.coder.com too somewhere around the 3-minute mark.
