Have you seen the ticket referenced there (#26169) It feels very random, 0 context of why he decided to set back that element to 12px.

Moreover, I wonder how these reporters batch spot and report these 2px errors...

I have submitted ​this new patch. For me that padding 10 to one side, margin 10 on the other side, adding 2 px there, 2 px here, everything simply feels very inconsistent.

I'm not an expert at CSS, but isn't more consistent to just stick to one or another overall?

Firstly, I would recommend you to ​checkout this image to understand the issue better for #63305 and #63306. Both tickets relate to the same kind of bugs, with the only difference of screen-sizes.

I think we should merge both tickets into this one. They are the same topic, and they should be sorted at the same time.

Simply adding props to @vijaysinh9094 and @kananiparth1326 for the submitted patch and good to go

#63306 was marked as a duplicate.

As per today's bug-scrub it has been considered that this change poses more risks than advantages specially for extenders that could have considered for both this version and #63306 a margin of two extra pixels and this may provoke misalignments in their respective extensions

Allegedly, I want to inform that there is an admin revamp under consideration, and it may come in 6.9 or 7.0.

For these, reasons, this ticket will be closed as maybelater.

Thanks to everyone who has participated in this report.
