I’d like to launch a vote for the integration of the patch from Bugzilla #50763  into the Trunk.
The implementation of fo:basic-link would deviate from the XSL-FO 1.1 Recommendation, and behave as if the following sentence were added to Section 6.9.2, “fo:basic-link”: “The extent, in the block-progression-dimension, of the content-rectangle of an inline-area generated by fo:basic-link, is the minimum required to enclose the allocation-rectangles of all the inline-areas stacked within that inline-area.” This sentence is borrowed, with minor modifications, from the definition of the maximum-line-rectangle in Section 4.5, “Line-areas”. A bug  has been raised at W3C and the implementation may be changed in the future to match the new requirements that may follow from its resolution.  https://issues.apache.org/bugzilla/show_bug.cgi?id=50763  http://www.w3.org/Bugs/Public/show_bug.cgi?id=11672 +1 from me. Thanks, Vincent
