[NTG-context] Space around comma in math mode

[w n]

Hi,

I am using
$ context --version
mtx-context     | ConTeXt Process Management 1.03
mtx-context     |
mtx-context     | main context file:
/opt/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv
mtx-context     | current version: 2020.01.30 14:13
mtx-context     | main context file:
/opt/context/tex/texmf-context/tex/context/base/mkiv/context.mkxl
mtx-context     | current version: 2020.01.30 14:13

I am seeing some space in the PDF output when using comma's in math mode.
The space is between the "," and the "2". How can I eliminate this extra
space ?
\starttext
Some text $1,23$
\stoptext

Thanks
