Comparing #2965 (Version 3) and #2970 (Version 4)

Bugs when cycling through ‘filtered’ revisions:

1. On page render, no matter how many children/criticisms a parent of the highlighted idea has, only the highlighted idea is shown – that’s fine so far – but the displayed criticism count may be higher if there are criticisms that are not being shown. So there’s a mismatch.
2. As you cycle through the parent’s versions, the children are suddenly not being filtered anymore, and the highlighted idea suddenly has siblings. Now the criticism count on the parent does always match the number of shown criticisms, but it seems arbitrary to suddenly not filter the children anymore.
