Created attachment 339806 [details] Fraction display under JavaFX using WebKit. https://github.com/javafxports/openjdk-jfx/issues/71 This bug seems to be specific to javafx, but I don't understand why ! It affects only MathML rendering since 2011. Only the vertical size of the RenderBox is bad. I tested RenderMathMLFraction.cpp and noticed that : Numerator and denominator heights are wrong and equal to 1. While numerator and denominator widths are correct. I tried to go further, but I not familiar enough with WebKit. I'm looking for any help/suggestion to move foward.

All childs height equal to 1 in RenderMathMLBlock ? RenderMathMLBlock: layoutItems : child height()1

I finaly found what's wrong with MathML lines overlapping. In fact MathML needs `platformBoundsForGlyph` implementation in FontJava.cpp. Continue to investigate becauseof bad alignment with fraction line for example.
