Tooltops are not displayed in the installer (or do not exist?)

[cpaelzer]

What happened?

I test installed mantic and while I knew that the icon at the bottom right likely would show me the console I was 1% unsure if you added something else and thought "let me just hover, the tool-tip will tell me".
But no tool-tip ever appeared.

I show the example with the "show console" button, but the same is true for all other UI elements.
Do the left/right arrows skip or revert something (No they just go through the slideshow).
What exactly does the pause button pause, ...

What was expected?

Especially on Icon-only UI elements tooltips could help a lot to overcome uncertainty, especially if people would be less used to our installers they'd be much more unsure without.

Steps to reproduce

• Download Mantic iso
• Run the installer
• Hover over the buttons
• => miss the verbose text, especially on icon-only UI elements
