Extra <br> tags are added in firefox when using code styling

[kerzsi]

E.g.:
Click on Bold button, write "test", press space, the input content will be:
<div><strong>test&nbsp;<br></strong><br></div>
instead of
<div><strong>test&nbsp;</strong></div> (as it is on Chrome)
That happens after space pressed

• Browser name and version: firefox 53.0.3
• Operating system: win10
