[NTG-context] footnotes when using RtL (Arabic)

[talazem at fastmail.fm]

I’ve run into a hiccup. In the previous MWE that worked with Woflgang and Hans’ patch, the notes were footnotes. However, if make them into linenotes, we run into a strange problem: the first note is typeset correctly, but all the remaining linenotes in that stream are typeset on the bottom left corner of the page. See attached files.

Best wishes,
Talal

I even tried mixing Arabic and English text in the RTL footnotes, switched on the “alternative=serried” option, and defined my own custom note streams — everything worked very well. The only thing that didn’t work is to mix, in the same stream, footnotes that are LTR with footnotes that are RTL. But I did not expect this to work, and I cannot think of a real world scenario in which such footnotes would/should be mixed in the same stream.
