Sourcemap warning: Unexpected generated column decrease

[TheSpyder]

I'm working with SlateJS in an app and am evaluating a switch to esbuild for bundling. However when I turn on --sourcemap in esbuild, I get a warning about Slate's sourcemap:

node_modules/slate/dist/index.es.js.map:1:162026: warning: Bad "mappings" data in source map at character 313: Unexpected generated column decrease
..."isLast","isInlineOrText","newChild","previousPath","oldAncestors","newAncestors","nextPath"],"mappings":";;;;AAAe,SAAS,eAAe,CAAC,GAAG,EAAE,GAAG,EAAE,KAAK,EAAE;EACvD,IAAI,GAAG,IAAI,GAAG,EAAE;IACd,MA...
                                                                                                 ~~~~~~~~~~
1 warning

Slate uses rollup to generate the index.es.js sourcemap, so I am assuming this is an esbuild bug, but if not I'm happy to log this with the appropriate project.

Thanks for the report! This should be fixed in version 0.6.34.
