Lighthouse dev tool is reporting an ‘unload listener’

  • I’m using the Chrome dev tool, Lighthouse, to optimise my website. I’m getting close to 100% but under Best Practices it is listing an Unload listener as an issue:

    Registers an unload listener
    The unload event does not fire reliably and listening for it can prevent browser optimizations like the Back-Forward Cache. Consider using the pagehide or visibilitychange events instead.

    I’m pretty sure this is caused by the WP Bruiser plugin.

    Is this something that you could address in the next release of the plugin, please?

    Thanks,

    Phil
