The rules for a component files are applied *after* \startcomponent
which isn’t the case for the example where in the first iteration
the "text" rules are applied and in the following iteration the rules
for a product file.

Moving \product … after \startcomponent prevents the loop but
the environment won’t be loaded anymore because the product
file isn’t loaded anymore.
