Table statistics dashboard and "Top Tables by rows read"

MickMcMickMc EntrantCurrent User Role Contributor
In the "Top tables by rows read" dashboard, reads from performance_schema.events_statements_history appears to constantly increase over time until PMM is restarted (see attached screenshot, although this applies to all of our monitored instances). I'm guessing this is an error with the way the metric is collected, rather than an accurate statistic. can you please confirm?
Edit: I should add that we use performance_schema as a source for query analytics, in case that makes a difference
