Description
Test scenario:
- 1-node cluster, 1 bucket
- Store 1 alive doc + delete it -> just deletion at seqno:2 in the default collection
- Create a custom collection and store a doc in it
- Run compaction (use cbcompact with the right params for purging everything immediately) -> seqno:2 is purged, the default collection becomes empty
- Create a view on the UI
View creation gets stuck forever.
Views looping on:
