Title is being set to an empty string on client-side navigation with SSR

[matiasperz]

Hey! I noticed that on this personal project of mine my <title> tag is getting emptied each time on client-side navigation. I only have a +Head.tsx file defined at root so should't be overridden by any page.

Digging into the onRenderClient.tsx I noticed that the title var that comes from the pageContext.configEntries is being set to an empty string if it returns a falsy value, so it always updates the head <title> tag. Wondering if it's safe removing this || '' at the end of the line.
