Single-fixed and multi-fixed components remove selection when space key is pressed

[vcalexa]

Steps to reproduce:

1. Select any option from the single fixed component(e.g. Skiing)
2. Press the space key once
3. Click anywhere outside the component

Actual behavior: the initial selection is removed Expected: Space key should have no effect

This also occurs on the multi-fixed component

This is actually trimming of space on focus-out
