[Plugin: WordPress SEO by Yoast] Focus keyword not found in page URL

The focus keyword found indication is unreliable.
Example focus keyword:web marketing for small business
Permalink:
https://thewebalyst.com/web-marketing-for-small-business/

I began with a longer permalink than the above, but which started with the focus keyword. This was:
https://thewebalyst.com/web-marketing-for-small-business-websites-seo-wordpress/

When this showed not found in Page URL I thought “oh, maybe it wants an exact match” so changed to the exact matching version, at which point it DID find it in the Page URL! Hooray… but later I accidentally edited the focus keyword, and it stopped (correctly). But since then, in spite of correcting the focus keyword it stubbornly refuses to show it as found.

I think it initially failing to find it in the longer permalink is probably the same bug.
