What's wrong ?
Sounds like a browser zoom is issue, make the browser zoom is set to 100% (ctrl + 0 or cmd + 0 for mac) should do this in most cases, otherwise find the zoom level in the settings
I always pay attenttion for it, because it's the most common problem i guess.
Yesterday I tryied with various zoomings and even wrote the properties one by one as you can see in the screen shot above.
Well, today I tried again what you said and it worked.
Cheers to you!
