Intermittent Focus Issue in 28.1.39

[Ryan Tomko]

I sometimes encounter an issue where I click on a SfTextbox and it appears to get input focus on the mousedown but then on the mouseup the input focus leaves the control.  I haven't been able to reproduce it yet, it appears to happen at random times, but I put in some JS debugging that I can check when the issue happens. This is what the JS log shows:

I will keep trying to reproduce the issue, but for now I have to reload the page to correct the issue.  The problem is that clicking into a textbox doesn't make the input focus stay.  I'm not sure where the focus goes to on the mouseup, but from the JS log it appears that the body element is getting the focus instead of the textbox.

This is in Blazor Server, .NET 9

Hallo.
I have too a similar issue. If I use the mouse, some visual effect.
If I move the focus to the SfTextBox using the TAB key then it works...
I'm using Blazor WASM.
It goes without saying, this occurs only in a specific dialog and I'm unable to replicate too.
