Arrow keys advance Preset Listboxes but do not activate the Preset or update Preset Values

[IBNobody]

Description of the bug

In the Print/Filament/Printer tabs, I often use the up/down arrow keys to select presets. This is extremely handy because it lets me check for uniformity across my customized presets.

This functionality appears to have broken in 2.7.0.

The up/down arrow keys will change the preset displayed in the listbox. For example, hitting the down arrow with "0.07mm DETAIL @MK4IS 0.25" selected will advance the listbox to "0.12mm SPEED @MK4IS 0.25", but the "0.07mm DETAIL @MK4IS 0.25" preset will still be active and all the preset values will be for "0.07mm DETAIL @MK4IS 0.25". Furthermore, attempting to save a copy of "0.12mm SPEED @MK4IS 0.25" will actually save a copy of "0.07mm DETAIL @MK4IS 0.25".

If you CLICK on the preset in the listbox, though, it will select the proper preset.

Project file & How to reproduce

1. Go to a preset tab.
2. Click on the preset listbox, and select any preset.
3. Press the down arrow on the keyboard.
4. Observe that the listbox value changed.
5. Observe that none of the preset values have changed.
6. Click on the Save icon.
7. Observe that the save action wants to save a copy of the original preset.
