Placing NoScript button into F29 menu breaks its grid layout

[Stevko]

I am not sure if this is the right place to report bug (what I think is a bug), but here it goes:
I used the fact that new Firefox menu can be customized and placed buttons of extensions there (instead of having them on the panel). However placing NoScript button there breaks the nice grid layout there (see screenshot: https://imgur.com/5MIHtv9 – I use Gnome 3 theme, but yes, I tried it with default theme and it still happens).

my advice is, to resolve the problem, don't place the noscript button there..
