Custom size is set to true. Vertical align is set to middle. Element height is set to have additional padding, in Cocos Studio it looks good without clipping.

What can I do?
I believe, setLineHeight function could help. But neither cc.LabelTTF nor ccui.Text support this function.

Create BMFont from TTF at runtime

I found acceptable workaround.
