fontawesome 5 facebook-f icon not correspond in window [fixed in 4.3.3]

fontawesome 5 icon - facebook-f - in the bootstrap studio window preview it doesn't correspond to the corresponding fontawesome 5. It is supposed to be an "f" without a square behind. in browser doesn't have a problem, it corresponds. only in the bootstrap studio browser window this problem occurs

Thanks for reporting this! Can you test it in the newly released Bootstrap Studio 4.3.3? We made some changes to the icon fonts that could fix this.
