In scrollable setting autoscroll=true won't work in some systems due to keyboard modifiers events from system

Is your issue REALLY a bug?

• My issue is indeed a bug!
• I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

Using the scrollable example, I added .autoscroll(true) to each scrollable and then running the program, I clicked the middle button, moved the mouse and nothing happens. I'm using linux mint. I examined the code and found that the mouse middle button click was happening but it was immediately being canceled. On further investigation I determine the canceling was happening at line 725,
| Event::Keyboard(keyboard::Event::KeyPressed { .. }| keyboard::Event::KeyReleased { .. })
In this statement, the keyboard modifier events are being checked too. In some systems, modifiers can be fired from the system. Therefore, I changed the 725 line to simply | Event::Keyboard(_) and all works ok now.

What is the expected behavior?
