For most of the properties that can take a percentage value, the percentage refers to the containing area's (or nearest ancestor reference area's) ipd or bpd. The only notable exception is font-size, which refers to the parent element. So if we take end-indent, for instance, if it's not specified inside footnote-body, then it takes the /computed/ value of the parent element (e.g., the block containing the footnote). /But/ if it has a specified percentage value, then the percentage shall be resolved against the footnote-reference-area. In many cases this will lead to the same result, but not when footnotes are declared inside lists, tables, block-containers, or if the region-body has several columns, etc. This issue is not related to lists and tables only, but is more general. If PageBreaker is left as is, then percentages specified inside footnotes should resolve correctly, but not inherited values. If we move the setParent call like explained above, then this is the other way around... -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
