New Pin Room Banner: Unavoidable performance and bandwidth issues at high pinned message count. #28041

Most users are unlikely to come across this or unexpected workflow
S-Major
Severely degrades major functionality or product features, with no satisfactory workaround
T-Defect
Z-Labs
Steps to reproduce
Opening a room with hundreds (700-900 in the tested cases) of pinned messages across a long time.
Outcome
What did you expect?
Regular usage without issues.
What happened instead?
Tanked CPU performance, stutter, slow loading of message history for a while, presumably while all the pinned messages are still being fetched. Whether or not a room is encrypted seems to affect little, if anything. Presumably depends on server + client performance and overall bandwidth.
