[NTG-context] Formula numbers in RTL mode

Hi Hans, I recall something like this was reported a few months back, and you said you were reworking math alignment mechanisms at the time. Now that you're getting ready for the Tex Live version, I want to bring attention to this issue once again, in the hope of getting it resolved. Formula numbers are not placed at the far end when in RTL. Here is a MWE: \starttext \input knuth \placeformula \startformula E = mc^2. \stopformula \righttoleft \placeformula \startformula E = mc^2. \stopformula \stoptext Attached is the result from context version 2017.05.14 19:09. Using \setupformula[location=left] gives similar results with directions swapped: output is as desired in LTR but slightly off the edge in RTL. Thanks, MHB
