nit: move dec into the other LocationBarDecoration overrides - (we usually
follow the order from the parent class too, so it could go between
`GetWidthForSpace` and `IsDraggable`, but some of the later stuff is already out
of order)

Then I'd put the comment into the .cc

Unfortunately I'm not following what you mean - can you re-explain what you're
asking for? And "dec" stands for "declaration?"

yup dec is declaration. Since this method is an override of a method on
LocationBarDecoration it should be grouped together with the other overrides on
LocationBarDecoration which  is just below; under "// Implement
|LocationBarDecoration|.

And when doing that, it's generally good to follow the same declaration order
that the parent class uses -- e.g. it makes it easy to see which methods a
subclass *doesn't* override by comparing the list.

Got it.
