Placement from child themes

I have a custom base theme (uses bootstrap) which defines a set of common rules in its file.

I noticed today that websites using my sub-themes (themes based on my bootstrap theme) are ignoring the entries in the from the parent theme. I was sure it used to work (not 100% certain though).

Can you please confirm if a sub-theme's will augment the from the parent theme, or does it completely replace it (thus needing to duplicate all the common placement rules from the parent theme)?

If it's the later case, would it be feasible to look at an enhancement such that child themes rules were in addition to the parent themes?
