doc_feature strange features

[MabezDev]

Not quite sure how this crept in, but it's a bit of a weird one :D.

[bugadani]

The fun part is: not every documentation has this (ESP32 does not). Could this be a rustdoc bug?

[bjoernQ]

interesting - if I build the docs locally I don't have it (I'm still on esp 1.89)

[bugadani]

Perhaps caused by rust-lang/rust#147153?

[bjoernQ]

interesting - if I build the docs locally I don't have it (I'm still on esp 1.89)

but even with esp 1.90 I don't see that locally 🤔

[bugadani]

No wonder, the change will land in 1.92 - rust-lang/rust#138907

The RFC hints at a few ways to hide cfg doc labels

[bjoernQ]

oh I thought we build all documentation with the esp toolchain - but for RV we use a "random" nightly ... that explains a lot to me
