MM transforms to ligature in vsvode

[shardnet]

there seems to be an extra undocumented ligature popping up in vscode.

the lower case m will have create a zero width ligature if two are chained together. "mm"

I have also noticed this issue. It happens in every application I have used with this font. It makes it difficult to use this font. For example, If I write the word "command" there will be a space before the first "m" and the second "m" will occupy the same space as the adjacent "a".
