I've tried the tooltip component in HTML element and the first time the mouse enters it doesn't show it.
This issue doesn't occur whit a RadzenButton.

You can try it on the radzen demo page, load it, and go directly to hover the html button.

I can reproduce it too. The first time you click OR mouseover a button there is no function. Ensure that you do not move the mouse over another botton before you click.

The problem is that in RadzenTooltip.razor the command await InvokeAsync(() => { StateHasChanged(); }); doesn't execute fast enough and so the following if (tooltip != null) results in false. @enchev Please reopen the issue.
