I consider this as an uncontroversial bugfix
=> I would like this to be in 1.23.X instead

Could you rebase this to said branch via running

npm run rebase-pr-to-1.23.X

[Zaid-maker]

That's a lot of changes??

[jmolnar-comparative]

I think somebody changed the target to 1.23.x; it was originally based on the main branch.

[jmolnar-comparative]

Needs to be rebased. Frank asked me to do that, but I've been too busy with my job

[jmolnar-comparative]

For context: my original PR was 1 commit, +/- 1 line

[CommanderStorm]

I guess then this is going into v2.0.

Think this can also be considered a "feature" as this strictly speaking adds functionality to the internal api and not to the user interface.

=> merging with junior maintainer approval.

@CommanderStorm I made a backport to 1.23.X here: #4757
