Please check your settings in Taskbar Inspector to see whether you have a specific configuration set for Edge. Image:

If not, please post a screenshot that demonstrates the problem.

Closing as duplicate.

Good that you noticed it before I began wasting time trying to reproduce it only with Excel.

On your video it looks like indeed the tooltip causes the issue, but you didn't show what happens when the tweaker is not running. The tooltip should appear even without the tweaker. It's just that when the option is set to default, I don't see why the tweaker would cause the issue - it shouldn't have any effect.

So you're saying that when the tweaker is running, but all options are off (set to default), the issue happens?

Can you please make a video recording demonstrating the bug?

Then I'll try to reproduce it on my computer.

Does it happen when the tweaker is not running? Does it happen when all options are off? If not, which option causes it?

Also note that Excel has several cases of special behavior regarding the taskbar. See this topic in which I link to several such cases, perhaps one of them is similar to yours.
