I have sent a couple of patches to fix it and open a discussion to see if this
behaviour is intended or is a spec bug: allowing different precision qualifiers
for block members in different definitions of the same shader interface is only
allowed in GLSL ES 3.1. In older and newer (GLSL ES 3.2) specs the precision
qualifiers should match.
