- Improvements to how Astro handles style updates in HMR
- Fixes a Svelte-specific HMR bug that caused Svelte component styles to be lost once a .astro file was hot reloaded
Improve HMR handling for styles, persisted islands (#3492) * feat: improve HMR handling for styles, persisted islands * Also using data-persist to keep injected <style>'s during HMR * Updating E2E tests to validate that .astro HMR doesn't blow away component styles * chore: add changeset * copy/paste error when cleaning up tests * big change - using inline <style> blocks instead of <link>s in dev * Updating tests that were expecting <link> stylesheets in dev * updating all E2E tests to use workspace versions for astro deps * TEMP: adding debug logging to see why the Ubuntu test only fails in CI * fix: Svelte styles are automatically handled by Vite, we can skip them in dev * fix: svelte is more interesting, we need Astro to inject styles only until hydration * avoiding extra HMTL noise by only including the data-astro-injected URL for svelte components * TEMP: ubuntu CI doesn't like the svelte HMR test... * disabling the svelte component test on ubuntu for now Co-authored-by: Tony Sullivan <tony.f.sullivan@outlook.com> 2022-06-06 18:39:48 +00:00			`---`
