Describe the bug
When starting from SSR generated HTML with
hydratable: true, hydration will remove the<title>element along with the other appropriate<head>elements, but will not add it back.Logs
None.
To Reproduce
https://github.com/johnmuhl/svelte-hydrate-head
Expected behavior
The
<title>should remain after hydration.Stacktraces
None.
Information about your Svelte project:
Independent of browser.
Svelte 3.17.0+
Severity
Pretty bad.
Additional context
This was introduced in #4082. The compiled component sets
document.titlefirst and then later removes elements matching[data-svelte="svelte-..."], and so the title is lost. The simplest way to handle this would probably be to not add the special SSR attribute to the<title>element at all, since as of #4250 we don't need to worry about there being more than one of that anyway.cc @johnmuhl @tanhauhau
