Pull Request for Issue #5095 .

Summary of Changes

Testing Instructions

[rich20]

It works, but only if is chosen with Crypsis the option bootstrap 2 icons and for Crypsisb3 bootstrap 3 icons.
If you use legacy symbols, you need for all categories own images, otherwise the other categories have no symbols.

With Font awesome (but that's another problem and has nothing to do with this fix) you see additional the flashing question mark.

I will re-do it on 5.2
