Is URI fragment required for Ignition to function properly?

[laacz]

Hi!

As ignition.js is compiled and contains lots of stuff, I could not figure out what is the purpose of the URI fragment, which is being appended when Ignition takes over rendering of the exception page. Is it required for Ignition to function properly or could it be removed?

It causes some small inconveniences when Ignition rewrites an already existing URI fragment and instead of a simple refresh, even a back won't work (it looks like that previous URI is not pushed to the browser's history).
