Why did you expect them to be blue?  Tooltips are special frames that
don't display any buffer, whereas face-remap-add-relative is
documented as affecting only the buffer that was current at the time
it was called.

More generally, face remapping is designed to allow buffer-local
changes to faces.  If you want to affect the way tooltips are
displayed, you should instead customize the 'tooltip' face or the
parameters in 'tooltip-frame-parameters'.

IOW, I don't see any bug here.
