Hello, not sure if it's a bug or just I'm not doing it right

I'm generating / obfuscating 2 different js files that are both loaded in the same script/page

options_browser.sourceMap = true; options_browser.sourceMapMode = "inline";

I can only see one of the two sourcemaps in DevTools, the one is labeled as "sourceMap"
If i manually delete the inline sourcemap (the one I see in devtools) and refresh the page, then I see the other one, labeled aswell as "sourceMap".

At this point, the only thing I can guess is that they are called the same internally and one is overwriting the other.
I have researched a bit about inputFileName but this only works if the sourceMapSourcesMode option has the value sources. (this option does not include inline sourcemap content)

As per DevTools AI , Google Chrome seems to support differents inline sourcemaps:
Chrome DevTools fully supports multiple files, each containing its own inline source map. This is a standard and widely used method for development.

Any thoughts?
