media metadata has been modified (prevents clicking one image's description
field right after having modified another).

Fix #8918

Fix #9057

Reminder: Suggestions were added in #7918 and are based on who you
interact with who you do not follow. E.g. if you boost someone a lot
from seeing other people's boosts of that person, it makes sense you
might be interested in following the original source; or if you reply
to someone a lot, maybe you'd want to follow them

Each suggestion can be dismissed
