SSR leftovers

[ang-zeyu]

Just a tracking issue, I think not much actionable here for now, especially as some of these might be fairly difficult / not worth the benefits to fix (the first 2 especially).

See #1534 (comment)

Just a checklist to track the follow-up tasks for this SSR PR:

• Integrate the re-rendering in SSR (due to source file changes) with Lazy serve: Track opened pages for dependency changes #1513 (a dev-ops only issue)
  Also see: SSR to resolve FOUC #1534 (comment)
• Fix the regression of hot-reload to live-reload (by looking into live-server to see how we can prevent live-reload specifically upon SSR re-rendering and outputting of files) (a dev-ops only issue)
• Find alternative to createLocalVue
• Discuss and resolve inline rendering issue for alt
• Resolve issue with mobile site-nav
• Fix minimized panel's minor regression in behaviour
• Hoist local script / style tags downward SSR to resolve FOUC #1534 (comment) (p.high)
• Retarget / remove unnecessary or inappropriate selectors in the algolia plugin
