Misleading UI on multiple layer vector dialog

[qgib]

Author Name: Johannes Kroeger (Johannes Kroeger)
Original Redmine Issue: 18144
Affected QGIS version: 3.5(master)
Redmine category:gui

1. I select a file with multiple layers inside in the Data Source Manager

2. I click "add"

3. @right after add.png@

4. I think that the first layer is selected as there is some blue in that line so I click Ok.

5. The dialog closes and no layer is added.

Instead I needed to explicitly select a layer (which is GOOD but not communicated well). If I click on one, I get a "proper" dark-blue selection (@really selected.png@).

Suggestions:

Do not highlight anything in the initial state of the dialog

and

Disable the "OK" button until at least one layer is selected.

3.5-master exhibits the same behaviour as described in the initial report. Bug is still valid.
