Mouse Backward and Forward do not work as expected

[m-zheng]

Hi,

Thanks for sharing these excellent key mappings that greatly increase my productivity!

I would like to report that all shortcuts to trigger the mouse backward and forward do not work even though they are recognised in Karabiner-EventViewer.

The gif below shows the key mapping - 🖱️B and +🖱️F cannot simulate the mouse backward and forward despite being recognised by Karabiner. This problem persists on Apple Applicaitons. For example, Safari and Finder. However, they work perfectly on Firefox and Pycharm.

Screenshots
This screenshot is captured without any mouse connected. It is converted from a 30s video which is also uploaded to dropbox.

The file structure in the screenshot is that Test1 contains a subfolder called Test2 that also contains a subfolder called Test3. At the time of recording, Test3 and Test1 have been viewed so that the < and > buttons are not greyed.
