Diagnostics are sometimes presented on the wrong line

[COCPORN]

Diagnostics are sometimes presented on the wrong line:

<Waa /> creates the correct diagnostic messages, Data type not found and Could not resolve type on the right lines in the editor.

However, missing a " creates the error on the next line:

<WhileEmpty Items={places}">

...will create an error on the line following the error for some reason.

The code that makes these calculations is in diagnostics.ts.
