fixes #13466

This PR changes the link preload behaviour so that it only ignores a link which has already triggered a preload. Previously, it would start ignoring a link the moment it was hovered on. This caused a link that only preloads on mousedown to always be ignored since a user's mouse would hover on the link first, causing it to be ignored on the subsequent mousedown event. This PR also fixes the data-sveltekit-preload tests that did not manage to catch this regression by changing the tests to use playwright mouse hover simulation instead of programmatically dispatching the mouseover event which didn't complete before firing the other events.


Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

  • It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs

  • Ideally, include a test that fails without this PR but passes with it.

Tests

Changesets

  • If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.

fixes #13466 (for real this time)

#13486 previously fixed the preload on tap not working by ensuring we do not skip checking the link until a preload has triggered. However, there's also the case where we have both preload link options: preload code on hover and preload data on tap.

This PR ensures that we still preload data on tap even after a successful preload on hover if the preload on hover was only preloading code.
