== Steps to reproduce
# Go to https://en.m.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units on a mobile device (also reproduced on https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units)
# Attempt to scroll or tap the menu
== Expected results
menu opens, page scrolls, etc
== Observed results
Page is unresponsive
== Environments observed
- Browser version: Chrome 73.0 , Firefox 66.0.2
- OS version: Android 9
- Device model: reproduced on Moto g7 plus, unsure of device of original report
== Notes:
- originally reported via email
- original reporters noticed a javascript task running for a really long time (~7s)
{F28619495}
- It appears this is at least in large part due to the pageIssues.js code in Minerva. As seen from the screenshot of the profiler, the initPageIssues function takes around 2.5 seconds to complete and blocks the main thread. During this time, many `insertBannersOrNotice` calls are made each taking around 100ms. Furthermore, if the initPageIssues function is returned early, I don't notice this problem anymore.
