RichEditBox: picture and content after the picture

Question

In Windows 10 1703 Creators Update a new bug appeared.

Steps to reproduce:

1. Load an RTF document with a picture into RichEditBox
2. Save it.
3. Save it again.
4. Reload it or open it with another app - you will see that the picture is gone and all the content after it is gone too.

I submitted this bug here in FeedbackHub app.

The question is how to avoid this bug or make a workaround?

Answer 1

This project on GitHub is to demonstrate the bug and to fix it.

After you save the document for the 2-nd time, the picture is gone, but the closing brace '}' for the picture block is still there, so all the content that comes after the brace '}' cannot be read.

So we simply remove the odd brace and restore the picture that was gone using the same document (but unchanged one).
