Yellow border on Adaptive cards tab

[RabebOthmani]

There is a little yellow rectangle that looks like a border? IT's just next the copy button and can be confusing to users as it might look like a button

This one is from the Monaco editor that is used to show the JSON here. It's not finding a schema for the JSON supplied and marking a warning, see the squiggly under the opening brace, along with a corresponding mark in the gutter.

I did some investigation and found that we can turn on the ability to load schema, but then I got a fetch failure. Might be simplest to disable validation or set the schemaRequest issue to off from the default of warning.
