"spaceless" error needs backport to 4.x

Here's a patch that resolved the issue for me.

I can make it a MR if that's easier, lemme know.

@AaronBauman thanks for the work.

I have tested your patch with D10 and the 8.x-4.x-dev of the Redix. It applies cleanly and fixes the issue. Changes reflect in the select.html.twig file.

Moving to RTBC.

This is fixed and will tag a new release shortly
