MouseDown and KeyDown are ignored partially when using a HTMLViewer

<https://xojo.com/issue/56107>

I found in the forum that this is not the first time that this is happening.
I attached a small sample project to the FC where this is also happening on our machines.
Unfortunately in our products this happens much more often as you can see in the screencaptures attached at the FC.

Maybe anyone has an idea how to “force” the behaviour or make it more clear to Xojo how to replicate the issue?

The bug is totally gone if I delete the HTMLViewer control or set the renderer to native.
