Swagger UI preview doesn't update on incorrect syntax

[malidiab]

To produce this at version : v4.17.0

1. Write a correct yml file.
2. The extension will update the preview correctly.
3. Now make a syntax error in one or more lines
4. The extension will keep showing the last preview , as there are no errors there. which is confusing.
5. Close the preview and reopen it.
6. the extension will not be able to show a preview.

I think it is better to either :

1. let the parser ignore the incorrect syntax parts and mark them on the preview as big red rectangles with an error.
2. just hide the preview or mark it all as incorrect, instead of leaving the last correct preview ( check number 4 above )

Hi @malidiab and thanks for a feedback!

We'll think about how to handle it best. Showing syntax error message every time is probably not the best idea - imaging that you're editing the document, and every time your document becomes invalid (say, you didn't put a closing quote yet while editing) it would flash an error message.

I agree however, there should be some indication there, perhaps displayed after a timeout...

I'll update this ticket once we decided how to proceed with this.
