<p style="margin-top:0;margin-bottom:0"><br>

<p style="margin-top:0;margin-bottom:0">While working on my bidiluatex package, I found yet another ugly bug. When \pardir and \textdir are set to TRT, the display math containing \leqno is shifted to the left by half of \hsize. Please see attached plain TeX
document.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">For now, one can fix this by setting \predisplaydirection to 0. i.e.</p>
<p style="margin-top:0;margin-bottom:0"><br>

<p style="margin-top:0;margin-bottom:0">\everydisplay\expandafter{\the\everydisplay\predisplaydirection\z@}</p>
