Sponsors block cannot show multiple class correctly

[madebyaris]

Describe the bug

When I add multi-class on the Additional CSS class(es) box eg: "test-1 test-2", on the front-end, it will appear as "test-1test-2" and the result should be "test-1 test-2".

To reproduce

Steps to reproduce the behavior:

1. Create a page.
2. Add sponsors block
3. Select list instead of grid
4. See the block setting and scroll down to advanced
5. on the Additional CSS class(es) meta, write 2 class eg: "gsk-wc-sp-list gsk-wc-5-sp", then save the page
6. See the page URL, and check on the class of WordCamp-sponsor, you will see that another class we input earlier now joins as one.

Expected behavior

It should appear as "gsk-wc-sp-list gsk-wc-5-sp" not "gsk-wc-sp-listgsk-wc-5-sp"

Screenshots

I already type it correctly and already split it with spaces

You can see, that the CSS is marge as one.
