This is issue html

This is a epub file, in which "10" is -webkit-text-combine:horizontal. If change to -epub-writing-mode:horizontal-tb, it will be correct.

In epub file, -webkit-text-combine doesn't work well. Please check my attachment, looks it will move a litter higher than normal.

With '-webkit-text-combine:horizontal' the "10" is rendered in a narrow font that tries to match the width of the glyphs above and below it.

With '-epub-writing-mode:horizontal-tb', the "10" is rendered as a wider block.

I have attached "desired.png" and "bug.png"
