Pausing with spacebar not working

Whenever I need to pause a video (like on youtube) I use the spacebar. But on viki, other than pressing the video screen, there’s no other short cut to pause the video. I tried pressing “P”/ “F”, and ctrl P. It still doesn’t work. I was wondering if it’s because spacebar doesn’t work here on viki?

It works for me.

Hmmm that’s weird…maybe there’s something wrong with my laptop
