Fix Issue-3955 Blurry Text

[yohan-choi-dev]

Issue #3955, there is a blurry text issue when resizing the window size or zooming in/out.
I found out that the blurry text is related to the font-size and line-height.

Interestingly, the font-size is an even number, it becomes blurry when the line-height is 1 but not line-height is over 1.1. In contrast, a font size is an odd number, text look blurry when the line-height is over 1. I fix the issue by adding line-height in ui.js.

Perhaps, it may need to be addressed in a different way. So I hope this code will be reviewed.

Thanks.

That is more of a workaround than a fix though, Is there any documentation (upstream for Chrome or so) about similar issues? Maybe we should add comments to that part of the code that documents why we had to do this.
