Seahorse can't sync keys with keyservers: Request Entity Too Large
Spotted by our test suite while working on #12689. That's the case:
- with keys.openpgp.org's Onion service (that my branch for #12689 sets as the default)
- in our test suite, when using keys.mayfirst.org as the backend
I can't trivially reproduce this with hkp://jirk5u4osbsr34t5.onion but I think it depends on the keyserver that the pool will give us: as the keys.mayfirst.org issue shows, this problem is not specific to keys.openpgp.org.
