@sabina-talipova At first glance this sounds good (particularly "avoid multiple expensive redraws on a single load") - but I'm not sure what this issue is actually asking us to implment.
If you understand the context of the comment, can you please flesh out the issue a bit more with some context and additional information?
Otherwise, we should probably close it.

Actually, I don't quite understand requirements of this TODO, but it seems to me that we should investigate possible issue mentioned in this comment. I would prefer to leave this ticket for a while and learn what happens, but don't spend too much time on it.
