In Google Docs, my text cursor will randomly bounce backwards on the page if I perform certain actions, such as pressing Tab in a bullet point list to create a subitem, setting the text to italic, or sometimes just clicking the cursor to the end of a document. Sometimes reaching the end of the line is enough to make the cursor jump back to a random position on the line. I have tried this in a new profile with no addons and the problem persisted. I could not confirm this in Chromium last I tried. (But I swear I remember it happening in Chromium once or twice before) I have confirmed it on my PopOS laptop and my main PC booted into both Linux Mint and Windows 10. I am running Firefox version 116.0.3 (64-bit).
