We need some more sizes of braces. The suggestions in bug 407101 and bug 414277 would resolve this.
Status: UNCONFIRMED → NEW
Depends on: 407101, scale-stretchy
Ever confirmed: true
Interestingly, the rendering is different on the latest Camino trunk. Only the smallest size under- and over-braces are used.
Created a webpage that shows this bug and how it screws up putting braces inside of table cells (Same as image provided). It looks like the brace's size is not given to the table so that the table can position the braces correctly, there should be a 3px padding. https://eyeasme.com/Joe/MathML/OverBrace_UnderBrace_Bug.html
Bug seem to be fixed as the attachment shows, BUT there seems to be an image degradation as the next attachment/comment shows.
Images from https://eyeasme.com/Joe/MathML/MathML_browser_test using Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-US; rv:1.9.3a5pre) Gecko/20100513 Minefield/3.7a5pre First image is of TeX, then next is Firefox 3.5 and the last is trunk build Notice that the underbraces are less defined in the latest trunk release.
(In reply to comment #8) > Notice that the underbraces are less defined in the latest trunk release. If you are referring to smaller hooks and thinner lines, I think that's just from rendering at small font sizes and from STIX fonts choosing to make the line thickness similar to the thickness of stems in other characters. Fixed after changes in bug 407101.
