[v4] ::first-letter reset causes inaccurate text selection

What version of Node.js are you using?

v20.9.0

Reproduction URL

https://github.com/mdillgen/tw4-test.git

Describe your issue

In this Tailwind version, some rules of the preflight (or CSS reset) have been extended by the ::first-letter pseudo-element. This leads to the – in my opinion undesirable – side effect, that rules for the ::selection pseudo-element (formatting of selected text) are not applied to the first character of text elements. The character is handled separately, somewhat out of the flow.

See the attached screen recording, which illustrates this issue.

Please note that the problem occurs at least in Chrome and Safari and does not occur in Firefox (MacOS).

Hey @adamwathan , thanks for your quick response and quick fix. Unfortunately, after the update, when I try to run the app, it throws an error:

Failed to compile.

An error occured in `next/font`.
