Crash in rendering code when double or triple clicking after a lot of uptime #419
Description
Not sure what exact circumstances cause this, but a file has been open in xi-mac for a long time (days) it seems to inevitably go into a state where double or triple clicking somewhere in the text view causes the frontend to crash. I haven't gotten around to reproducing the crash with a build connected to the Xcode debugger but here's a trace from the macOS crash report:

Given how long the issue takes to manifest itself it might well be caused some endless source of Fun such as losing our rendering context during sleep mode.
