Hello
I am seeing this behavior on a random basis. Its only in Blazor Server. The tooltip on a grid sometimes gets stuck and then the tooltip seems to append fields as you move over different records. I cannot reproduce in a sample as it appears to be intermittent.
Maybe something to do with the implementation? Does it do a signal R round trip on ever hover?
Anyway, my guess is that you are not going to be able to help with this one, but at least it can go on record.
Thank you
