Bold Text not showing in Editor Field

[techteam-pro-discount]

Im coming from ckeditor 4, in the old one you could see the text you put as Bold was also in the Editor shown as bolt.
in the current version that isnt the case, ill include a image showing what i mean.

@techteam-pro-discount it works fine in the demo project in this repo:

Without any example code or config to reproduce it it's pretty hard to track down your issue
