CI "Develop" fails with diff on bindata.go file (containing gzipped JS)

[EskoDijk]

The CI "Develop" fails often, recently, due to the 'diff' operation performed on bindata.go.
The offending (different) line is in the gzipped JS produced by webpack.

Possible fix strategies:

• Use fixed/known versions of all library dependencies that get included in the JS build
• Use fixed/known versions of all nodejs/webpack/... build tools to avoid output code differences
• Use "hashed" module IDs or chunk IDs for webpack - tried in PR Webpack config update to 'hashed' module IDs #736 with hashed module IDs
• Remove the diff operation from the CI test (find another way to ensure the developer has built bindata.go prior to submitting the PR)
• Ignore the error

Based on a peek into the differences of the gzipped JS in bindata.go, it looks like the code is really different at some places. I.e. not different variable names encoding, but really different code. This could point to a mismatch in library dependencies that are used , or different version of some build tool.
