[SpeedDial] Interesting keyboard behavior

[amaslakov]

When using keyboard, when I open a Dialog from a SpeedDial, close it and try to navigate SpeedDial items with arrow keys, the direction inverts. And the ToolTip is also a bit off.

• [ x ] This is not a v0.x issue.
• [ x ] I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

The arrow keys act as usual

Current Behavior

The arrow keys act as if they were inverted

Steps to Reproduce

1. Tab to the SpeedDial button (it will open)
2. Use arrow keys to select Print item
3. Press space to open the Dialog
4. Press esc to exit the Dialog
5. Press the down arrow a couple of times

This is all about what key is pressed first. This was discussed in #12725. #12725 (comment) should be the most comprehensive explanation for the current behavior.
