[NTG-context] Strange behavior in math mode: < and minus sign give leftarrow

Hi Hans,

While testing old documents with lmtx, I noticed that with recent versions of mkiv, as well as LuaMetaTeX, there is a strange behavior in math mode: when the characters < and - follow each other one gets \leftarrow… This is embarrassing when one writes inequalities for negative numbers.
So one has to separate them in order to obtain with curly braces. Can this be fixed or is it intended ?

$\alpha < -1$ 

$\alpha \leftarrow 1$

$\alpha < {-1}$

$\alpha {<} - 1$

Best regards: OK
