[Bug 7369] if context font is set to '' or null, the font from the css should be used. In this case, you have no idea what font is being use, so measureText should return a height of the font, as well as the width so that proper displaying can be done.

Can't you figure out the em height by getting .font and parsing it?

I mean, I agree we need to improve the metrics in due course, but it doesn't
seem that it's as pressing as is described above.
