Missing spacing on long name ellipsis in multiselect

[raimund-schluessler]

nextcloud-vue v0.11.2.

With nextcloud/tasks#412 there is a space missing in between the first and second part of the names in a multiselect, see

("showfull" instead of "show full" and "hidethis" instead of "hide this").

This is because the space is cropped for these two entries, whereas it is correctly shown for the second string.

Edit: The string is split correctly, but the space ends up at the end of the first string, which is set to white-space: nowrap;, so the space is not shown there.

would need white-space: pre;.
