About languages plugin : react code

[pandacase]

The React code .jsx & .tsx in Github repo are recognized as javascript & typescript.
But the languages plugin recognize them as JavaScript & TSX respectively, see my generated-svg :

I suppose that the mapping rule is { jsx: javascript, tsx: typescript } or { jsx: jsx, tsx: tsx } (both is ok and of course the first one which is as same as github is better), but the { jsx: javascript, tsx: tsx } is ugly.

Custom languages name tsx:typescript seems not a sustainable way, the typescript language itself has held a place.

Is that a potential bug?

I had conducted a test yesterday and got something unexpected:

In my this repo, i first commit this 300 lines file as a .jsx file deliberately (although it is a .tsx file in fact).

After rerunning my generating workflow, the number of JavaScript lines in most used languages changed from 3.7k to 4.0k, which indicating the .jsx code is recognized as javascript.

But later I pushed a new commit changing the Globe.jsx to Globe.tsx, but now the JavaScript lines remain 4.0k ( I suppose the JavaScript lines should have gone back 3.7k and the TSX lines get that 0.3k; In the same time I did not commit any new js or jsx code in any repo )

Hope this additional info would help : )
