3f73251df5 reworked the way `offsetMode`
is handled, to allow reactive `ComputedRef<boolean>` in addition to a
simple `boolean`, so that custom emoji search could easily switch
between the faster `sinceId`/`untilId` pagination and the slower
`offset` as needed.
Or it would have, if I had written the correct expression! I wrote
`props.offsetMode` instead of `props.pagination.offsetMode`, so it was
always `false`
I have *no idea* how I didn't notice, I swear I tested it ☹
Anyway, factoring out the nested ternaries makes the whole thing
clearer and less prone to mistakes. And I have tested it, this time.
