// StreamJsonRpc has both Serial and Parallel requests. With WithContentModifiedSupport(true) (which is default) when a Serial
// request is made any Parallel requests will be cancelled because the assumption is that Serial requests modify state, and that
// therefore any Parallel request is now invalid and should just try again. A specific instance of this can be seen when you
// hover over a TagHelper while the switch is set to true. Hover is parallel, and a lot of our endpoints like
// textDocument/_ms_onAutoInsert, and razor/languageQuery are Serial. I BELIEVE that specifically what happened is the serial
// languageQuery event gets fired by our semantic tokens endpoint (which fires constantly), cancelling the hover, which red-bars.
// We can prevent that behavior entirely by doing WithContentModifiedSupport, at the possible expense of some delays due doing all requests in serial.
//
// I recommend that we attempt to resolve this and switch back to WithContentModifiedSupport(true) in the future,
// I think that would mean either having 0 Serial Handlers in the whole LS, or making VSLanguageServerClient handle this more gracefully.
