Bug description and reproduction

1. Add a system:hash predicate with at least one hash to a search.
2. Copy hashes from one or more files not listed in that predicate using share→copy hash.
3. Attempt to add more hashes through search→edit on the predicate, scrolling to the end of the hash list and hitting enter to start a new line, and pasting in the new hashes.

Expected result: The additional hashes are added alongside the existing ones.

Actual result: The original hashes are deleted and replaced with the new ones.

Note: this only happens when prefixes are present in the pasted text.
