Broken ligatures in headings caused by CSS -> letter-spacing

It took me a while until I figured out why the ligatures were broken in the default theme.

There is a CSS default in the base theme that breaks ligatures for headings it’s [letter-spacing], I’d propose to remove it from the default theme.

Tested with Cascadia Code on windows.

A workaround is custom CSS with this.

* {
    font-family: "Cascadia Code", monospace !important;
    font-variant-ligatures: normal;
    font-feature-settings: "liga" on;
    text-rendering: optimizeLegibility;
    letter-spacing: normal !important; /* FIX LIGATURES IN HEADINGS */

I don’t generally take CSS problems in bug reports. If this is an issue in the insider build, please talk about it on discord in the insider channel.

If this is an improvement, it should go in feature requests.
