Bold and italic not refreshing

[madsenfr]

Hello,

This time I reproduce on the default tab "Welcome to Markdown" 😉

1. Select the word "Features" use the "B" or "I" button.
2. Markdown code is modified, but the preview panel doesn't reflect this change.
3. Edit the markdown manually and it works.

All the toolbar options have crashed, and I am trying to fix them.
