Steps to reproduce

Check playground reproduction and hover over a variable (eg. page). See that nothing is happening. No Tooltip with type info and no intellisense for the whole component. Also, syntax highlighting is not working correctly either.

Remove the v-once inside the v-for loop and notice that now all mentioned problems are gone.

Placing a v-once on a single element (no v-for) works as expected.
So, it is only a problem when inside a v-for loop.
