there is a bug with the hamburger menu on Microsoft edge. If you click on a “svg path” (a grey line) it reloads the page. If you click between the lines, the hamburger works normaly.
Tested here on the meta (zooming the page helps to reproduce).
Right. Looks like clicking a SVG path in Edge doesn’t execute the action. I can reproduce it with every FA5 icon.
Thanks for the report. This commit should fix the issue:
For the record, I could reproduce this on Edge 17, but not on Edge 18 (see also the related Microsoft Edge issue ticket).
