Window goes on top but does not get focus

I have recently experienced an annoying behaviour which I think was not occurring before.

I have in dconf 'click-action' set to 'previews' (I like this behaviour).

When I click an open app icon in the dash-dock having several windows open, a preview of them appears as expected. When I click one of these previews the corresponding window gets on top as expected. But this window (call it A) does not have focus, which is unexpected.

Expected behaviour : window A gets focus

Actual behaviour : window A does not get focus

Why it matters: When I start typing text it types in the "wrong" window (I mean the window that had focus before while I am expecting to modify the text in the window that just went on top) and if I do not pay attention I may get into trouble by modifying files I do not want to modify. This could actually cause some serious trouble to an unlucky person, quite hard to debug if they do not know the cause.

Do not get confused: there are 'focus-...' options in 'click-action' but they concern what happens when you click the app icon. I am referring to what happens when you click the preview image, which is a different thing.
