@Agnibaan can you attach before and after screenshots of what this change fixes? Thanks

It does not work as expected.

1. There are three different list views. One per syntax type (Date, Counter, ...). So you need to set text wrapping property in each list view.
2. The text can't not wrap because the description grid column of the list views is to wide and exceeds the flyout wide.

This is how it currently looks:

And this is what we try to get:

(This screenshot was made with a fixed grid wide for testing.)

But while debugging I saw that there is a vertical scrollbar on the bottom of the flyout. Not sure if we should add wrapping realy. But I think with wrapping it looks better.
