Research direction

Search the repository for the .toLowerCase calls mentioned in the issue and trace how tag and attribute names are compared. Determine where an optional case-sensitivity setting belongs, then verify that the provided lowercase and camel-case JSX examples compare differently when enabled while existing behavior remains unchanged by default.

Written by the indexing model from the issue text.

Description

According to modern frameworks sometimes we need to check generated JSX and <button tabindex="1"></button> is not the same as <Button tabIndex="1"></Button> (notice the upper-cased i letter in index), etc.

Prob I can make a PR if you point me where are .toLowerCase call I need to disable and where I can begin.
