Re: r2l alignment and linenumbering conflict?

Hans, the beta is a solid step forward regarding bidi and Arabic support, and not just in footnotes. Thank you.

However, it appears that my earlier declarations of ‘problem solved’ were a bit premature.  Footnotes display everything correctly, but not linenumber notes. Using the three bidi methods of \setupdirections[bidi]:

- ‘default’ orders the linenumber notes and their texts right-to-left, but any number therein is reversed (4102 instead of 2014).

- ‘one’ does not render either the note block nor the individual notes' texts right-to-left.

- ‘two’ is identical to method ‘one’.

Compare these to regular footnotes, where everything is rendered correctly as of this new beta.

Below is a minimal example with resulting PDF output.
