Meta-tag suggestions aren't present if preceding meta-tag exists.

[Neonalig]

Perhaps as a form of optimisation, Agent Smith appears to not suggest meta-tags after a meta-tag is first found in the documentation. This however forces users to add meta-tags manually back-to-front otherwise suggestions disappear.

1. Two suggestions are present. 2.a If the first suggestion is used, the second disappears. 2.b If the second suggestion is used, the first suggestion still stays.

This forces users to always implement suggestions in reverse order.
