Describe the feature

Zed	Vscode	Webstorm

As you can see from the images in this case the icon is aligned to the letter a, but as you can see in webstorm maybe it would be more correct to align it to the p and g, that is characters that have a lower base.

Is the zed icon aligned to the top of the text?

Hey! Thanks for flagging this; there are a lot of improvements we want to make to the tab component. My intention is to soon tackle them all at once. But technically no, the item isn't aligned at baseline now, it's just that the icon container is glued to the top of the container that holds the icon and label.
