Scrollbars are behaving inconsistently in 'Detail view'

[HEskandari]

• Unnecessary scrollbars should be hidden.

This is a split of #624.

@Particular/serviceinsight-maintainers This is already done as a part of #692 where I opted using content wrapping instead. That means the content will get wrapped if larger than available width and no horizontal scrolling will ever appear.

This is the only reliable and low effort way I could fix this with. I'm happy to send a separate PR for that, but it is basically setting one property.

@HEskandari I think it's fine for the fix for this to be in the same PR as the fix for #643. I've marked the PR as fixing this issue too.

If we're going to turn off wrapping then the dialog should be resizable.

Come to think of it, the dialog should be resizable anyway.

Can we deal with that in another issue? This issue improves the window, even if it doesn't contain all possible improvements. IMHO, we can switch wrapping back on and release this.
