Feature suggestion: Only disable spelling and gramma check in fenced code blocks

Normally, when writing markdown I would like spelling and gramma check enabled,
but when I have to add some fenced cold blocks in the markdown, they are very likely
to trigger the spelling and gramma warnings due to arbitrary naming in programming:


In the picture above, wrng word in normal paragraph shows both spelling and gramma warning,
this is great and expected. But for the same word and the GetWrngWord in fenced code block,
I would like them to have no warnings.

I think this should be the default behavior, or at least there should be a
disable spelling and gramma check in code blocks option in the editor preference,
if you prefer diversity over uniformity.

I ran into this today. It would be helpful to optionally disable spell/grammar check in both fenced code blocks and inline code.
