Unexpected space in math between invisible element and text

[EpicEricEE]

Description

(Partially) a regression on main, using 084a061

#let size1 = context measure($ "abc" $)
#let size2 = context measure($ #metadata(none) "abc" $)
#let size3 = context measure($ #metadata(none)"abc" $) // Note missing space

In 0.11.1, size1 == size2 == size3, but on main size2 > size1 and size3 == size1. This is also visible when rendered:

As the metadata element isn't visible, the space between it and the text should not be kept.
The same happens for other invisible elements, such as counter or state updates. However, with those elements, the space is also there in 0.11.1.

Addendum: Another instance of this issue is the fact that the following to sizes are not equivalent. This was also already the case in 0.11.1.

#let size1 = context measure($ #metadata(none) = 0 $)
#let size2 = context measure($ = 0 $)
