On Linux the Tor Browser .desktop launcher sets wrong path for icon

This line has the wrong path:

Icon=/home/chris/Software/tor-browser-linux64-8.0_en-US/tor-browser_en-US/Browser/browser/icons/mozicon128.png

the location is /browser/chrome/icons/default, not /browser/icons/. Corrected:

Icon=/home/chris/Software/tor-browser-linux64-8.0_en-US/tor-browser_en-US/Browser/browser/chrome/icons/default/mozicon128.png

I don't know how to fix this in the .desktop file without it being rewritten with the wrong path.
