Rollup: (!) Broken sourcemap Plugins that transform code (such as 'VuePlugin') should generate accompanying sourcemaps

[SumNeuron]

This might be a repeat (sorry if that is the case), I saw several issues for sourcemap issues...
To be honest, not quite sure what that means and why it is an issue...

searched for broken sourcemap in issues results in no issues,

but searching for sourcemap gives

• add postcss document; #139
• How do you enable sourcemaps for CSS? #92
• Add source map support #24

which suggest that it is fixed?

Sourcemap support is not yet there.

Fixed in #215
