I’m running into a max line length of 5000 lines for viewing logs in the GUI. Is this a configurable item?

I’m using 8.3.6.

Very long log files can potentially cripple a browser-based GUI, and what to do about this is still an unsolved problem.

The limit is not currently configurable. For the moment, you have to go to the file on disk, or use `cylc cat-log` in the terminal, to see more than 5000 lines.
