Magic Trackpad causes high but varying input lag

Description of the issue:
How can this issue be reproduced?

I’m on 1.58.127 stable, macOS 12.6.9, mac mini w/RX5700 egpu. My usual window count is high, 200+, however I experienced this with as low as 20 windows open.
Whenever I am using my 2nd gen Magic Trackpad (flat gray slab), I am experiencing varying amounts of lag in input event handling both on websites and the browser chrome. As soon as I switch to a generic USB mouse, the lag is gone. The lag varies from site to site, thus I think it might be related both to input event type handling and the amount of event handlers alive on a given page. No other applications outside Brave experience this issue (e.g. Terminal, VSCode, Messages). Restarting the whole computer, or just the trackpad, or using the trackpad as a wired device - i.e. plugging in the lightning cable - makes no difference.

Expected result:
Browser input lag does not vary based on input device type.
