If you forget to type a semicolon at the end of a statement in Visual Studio, the squiggle will be placed at the end of the line, after the last visible character.

How do you get a similar result with SyntaxEditor (using a custom parser)? My expectation would be to create a ParseError with a PositionRange that somewhow includes the newline, but I can't figure out how to get it to work.

See also the C# editor demo in the sample browser that shows the same problem - the syntax editor on line 22 is invisible in the editor.

Hi Anders,

Thanks for letting us know about this.  It appears to be a bug introduced in 2019.1 when squiggle line rendering was refactored as part of our vNext updates.  We've fixed it for the next build.

The latest build of this product (v2019.1 build 0683) was released 1 month ago, which was after the last post in this thread.
