Quill emoji pane flickering over editor with clicking issue in comments

When I start a comment and select the emoji button in the Quill editor, I am getting a flickering problem with the popup emoji window (#emoji-palette). There is some kind of window/div/frame issue where I have trouble clicking on the categories or selecting an emoji. The emoji window is clipping when it runs into the following post on the timeline. On mobile, it goes underneath that next post at its start. I tried changing the width of the window in custom styles. But that didn't solve the issue. I notice it doesn't happen on this site. I'm not sure if this was something that was fixed post-UNA 13? I attached a screenshot. But the Windows screenshot tool doesn't capture the flickering.
