Attempting to reformat a Razor page using Ctrl+K, D always fails with this exception below. I tried to upload the source file, but .cshtml is a disallowed extension, so, ehhm, yeah...
StreamJsonRpc.RemoteInvocationException: Ran out of formatted lines while trying to process formatted changes after 137 lines. Abandoning further formatting to not corrupt the source file, please report this issue.

Thanks for logging this issue! For these cases, we have some extra logging that you can enable that will capture all of the information to allow us to reproduce and fix the issue in a test. If you can turn on the extra formatting logging, run the format operation again, and upload the results to this issue, we’ll be able to fix the problem ASAP. The extra logging information is in this doc: https://github.com/dotnet/razor/blob/main/docs/Formatting.md#turn-on-formatting-logging
We really appreciate you taking the time to do this, and help make the product better for everyone.

I found a minimal repro case just now:
This works as expected:
@page
@{
Func<(bool b1, bool b2), object> o1 = @<text>
<div></div>
</text>;
}
But this triggers the exception:
@page
@{
Func<(bool b1, bool b2), object> o1 = @<text>
<div></div>
</text>;
Func<(bool b1, bool b2), object> o2 = @<text>
<div></div>
</text>;
}
(In fact, you don’t even need the @page, just leaving that in to give some context on the location of the code, although that doesn’t even seem to matter too much)

Thanks Michiel de Bruijn thats all I need! I’m going to move this over to our GitHub repo and will fix it. Thanks again for the report and the repro example.
