[Bug] org-in-src-block-p returns t when not in source block

[No Wayman]

When on an empty line before a source block, org-in-src-block-p 
correctly returns nil.
However, when on an empty line after a source block, it returns t.
This is reproducible on my end with both the built-in version of 
Org and 9.7-pre.
