rustdoc: single comma is put on newline if it occurs after item in double ticks

[virtualritz]

Problem

Here is a part of the documentation in my fork of the colstodian crate's lib.rs:

//! If you also have alpha (i.e. four values instead of three), then
//! [`Color::srgba_u8`], [`Color::srgba_f32`], and [`Color::linear_srgba`]
//! are the equivalents of the above with an alpha component.

And here is how that gets rendered/formatted in the docs:

Note the lonely comma on the 2nd line, this should be connected/stay with the Color::srgba_f32 item at the end of the previous line.

I presume this is a CSS issue rather.

I investigated it and found that it is caused by display: inline-block which added to .docblock p code (It was introduced in #132183). If you turn off the style in the code tag on your web browser, single comma will not be shown.

So we should remove the style, but I'm not sure why we had the error described in #132183, how the style solved the error, and what is the alternative solution.
