The _scriptDir (pre patch) / _scriptName (post patch) variable is used to populate the scriptDirectory variable, which is not used anywhere (at least no references to it other than assignment). document.currentScript is already used inside the code to populate scriptDirectory, before unconditionally replacing it with the value of _scriptDir.

@calixteman Why did you introduce _scriptName instead of deleting the use of _scriptDir?

Unfortunately, almost all the js in this file is generated by emscripten.
The only js I added is:

• https://github.com/mozilla/pdf.js.openjpeg/blob/main/src/myjs.js
• https://github.com/mozilla/pdf.js.openjpeg/blob/main/src/mypre.js

So it's a bug in emscripten.
