I'm trying to add a success checkmark image to a tab in a layout group once the user is done with the tasks inside the tab.

I'm using a declare expression to change the value of the property to "testTab1withImg <img src=\"webwb/greenconfirmation.png\">" Otherwise it will be "testTab1" the value does change in the UI without the image so it's not a refresh issue. 

This is how it displays in the clipboard: it ignores the HTML when it displays.

this is how it displays in the UI:

The only way I'm able to display it in testTab2 is by hardcoding it as text:

I tried changing the UI control of the property to DisplayAsLiteral and that didn't work either. I also took a look at the HTML and there is no trace of img or anything, it seems that the property ignores any HTML when it displays.
