Reallocation is needed if a single chunk grows in size, even if total allocation size stays the same or is lower.
I was able to reproduce #16383 and confirm this was the cause of the issue. Had to use a remote machine with more VRAM though and it took few tries. This is a cleaned up version of the fix that I haven't verified again so far - can probably do it later today.
Also added a simple test which triggered the same assertion prior to the fix.
