I noticed when going from the latest stable release (13.7) to the development version, that the performance of zooming in a large line plot (using peak auto-downsampling, but I'm unsure if that was relevant) was significantly worse.
By binary searching commits for the issue, I found that it occured after commit no d13e2ce, which should be purely about documentation and linting.
The offending line caused "all_finite" to never be updated, and stay as None forever.
