It's been a totally normal workflow for me to open a ticket and then not try to write into it for a day or more as I'm thinking about how to resolve it. This used to work, but presumably a Trac update has now caused it to set a session token in my browser, which is now expiring before I enter my changes? Worst part, sometimes when I get this message, I'll then use Safari's back button to try to go back to the form, copy what I wrote, reload the page, paste it back in and try to submit again. But already at the first step, after I've hit the back button, the missing token message appears there too. My changes are lost completely and I have to redo / retype them. Is there a way to restore the prior behavior?

Not much the server can do for you here... Sessions expire, especially when you quit your browser. If you're restoring old tabs, and the tab actually queries the server for a fresh copy of the page, the token would be different than what you had, but valid. That might fix your workflow.
