It's mostly for long words. As you can see in my .gif
The reason i am copying paste is because there is "no set all tags to"
and also you can't copy and paste tags. So the only solution is too write it out first:
thebest car, joeyiscool, msn
without a comma at the end and then copy and paste it in all the boxes and simply add a comma to make it tags
But it doesn't paste well inside the tag box. It's almost as if the tag box is small. Or the internet doesn't see the big box space .
Have a try. I am using Chrome
