Investigate webpack v5 chunk names

[tobiu]

It seems to work fine in dist dev & prod, but I noticed that the chunk names in prod are no longer increasing the way they were before. There are pretty big gaps inside the numeric names.

v5:

It might be intentional and does not cause issues (except slightly longer file names).

Tagging Tobias @sokra to verify.

Tagging @h1b9b as well.

Thx for your input & best regards, Tobias
