Thanks for the bug report! Are you able to isolate the XAML snippet causing this issue and share it?

Also, can you share some versioning information to help us debug?

Version Info (please complete the following information):

• OS: [e.g. Windows 10 (1903), MacOS (10.15) , Ubuntu (19.10), etc.]
• Visual Studio: [e.g., VS2019 (16.4.1), VS for Mac (8.3.11), etc.]
• XAML Styler: [e.g., Extension (3.2001.0), Console (3.1912.0), etc.]

Almost forgot about this...

OS: Windows 10.0.18363 VS: Microsoft Visual Studio Enterprise 2019, Version 16.7.4 XAML Styler: Extension 2.2008.4

This is a workflow document (and this is just one of them failing).

@trivli, is it solved with #453?
