The problem is that we want to support webpack 4 and webpack 5.

Unfortunately that's not possible for this breaking change.. we will need to write a new dedicated webpack 5 version to solve your issue.

Can you please see if this is fixed with [email protected] ?
Please see also #1527

Not in 5.0.0-alpha.3, although it may be fixed in 44621d892ad544d2a0c27e7642dd973c417a6ae6.
