Spacing doesn't update on first load for font resource pack

So after loading resource pack that changes font and uses different glyph size than current spacing, just breaks, on first load it is. After entering/exiting a world or game than initializes second load of this resource pack, spacing fixes. 

This bug happens after enabling or disabling a font resource pack. So, for example, if I enable my font resource pack, update spacing, and disable it, spacing of this resource pack will stay until I enter/exit a world or the game 

The resource pack that I used and screenshots of the bug are attached to this post.

This how it should look like:
