[audrasjb]

There is an unwanted space in the margin declaration of the styles printed by the print_emoji_styles() function.

I think the margin is only intended for the sides (it had been 0 .05em 0 .1em before r31786).

However, we still could add the leading zero before the decimal point:
margin: 0 0.07em !important;

[audrasjb]

Hooooo good point, I think I was confused because the leading zero was missing :D
Editing the patch accordingly

Patch refresh

Refreshed in 54284.1.diff

Indeed, the leading zero suggested by WPCS is less confusing :)

New explanation suggestion for the changeset:
Formatting: Coding Standards: Add a leading zero in the CSS declarations printed by the print_emoji_styles() function.
