Tech tip - bug from using old version of Chrome's Lighthouse

Warnings from Chrome's Lighthouse turned out to be bugs from using an old version of Chrome used for Windows7.

Lighthouse said: 'heading elements are not in a sequentially-descending order'.

I can get round this by using the 'Lighthouse' option at 'webpagetest.org'. Or I can go to a neighbouring libary that runs Windows10 and the latest Chrome.
