Fix #9653 force load of font when fontAwesome css is loaded

[MV88]

Description

the issue was that the font (.woff etc) was not loaded until needed this caused this issue here

i've tested also loading directly .woff but in my case it was not fixing the issue, but with .woff2 it was.

we might add a second script for loading also .woff
