display property changed instead of font-display

can you explain how this change is related to the change in microsoft/vscode#131396? That change altered the font-display property, which controls browser timeouts in the case the font is slow to load. This change alters the display property, which changes how other text on the page is laid out relative to the codicon. The two have no relation to one another as far as I can tell.

This change seems quite undesirable, as it puts the codicon in its own box that fills the entire width of the container it's in instead of keeping it inline with the text around it. Is there any case where we want this as the default behavior?
