There is similar old bug https://bugzilla.opensuse.org/show_bug.cgi?id=500988

When you use the command like:

zypper search --provides --match-exact 'kernel-desktop=3.16.7'

zypper ignores capability command part and instead shows *all* packages with
the same name only, but not with the capability specified in the search query,
like this:

v | kernel-desktop | pac-> | version1   | x86_64 
i | kernel-desktop | pac-> | 3.16.7-7.1 | x86_64
v | kernel-desktop | pac-> | version3   | x86_64
v | kernel-desktop | pac-> | version4   | i686
v | kernel-desktop | pac-> | version5   | i686
