I really don't know if I can describe this well in words, so the below link will take you to a screen capture of my desktop doing the deed. I apologize for 'singing' at the end my friend didn't realize I was recording, and I'm not sure how to edit the video to cut it out.

The problem I'm having is with several sites causing the extension to generate a scrollbar on the right-hand side. I'm assuming that this is because the 'Fill', 'Copy', and 'Edit' parts that show up in red font are slightly larger thus requiring the scroll bar to fit into the display area. As a result of this font it shifts the buttons slightly to the left when you mouse over them. As the buttons move to the left, it takes your mouse pointer off the button, and the additional text (Fill, Copy, Edit) disappears which then lets the buttons shift slightly to the right back where they were. The friend singing also checked his LastPass and it does the same for him, but on a much harder difficulty to get it placed. The major difference between our system displays are that he runs in 4K resolution, as opposed to my 1920x1080.
The only thing I haven't been able to figure out is why the live.com site doesn't do it. I thought it might have to do with the LastPass 'name' length for the site, but for "Nebula" for example I tried shortening it to just "Neb", well under the character count of "live.com" and still had the same issue. I've tried uninstalling the extension and that didn't seem to help either. Also, while the video above is using Google Chrome (Version 87.0.4280.88), I've confirmed the same experience on Microsoft Edge (Version 87.0.664.57).
This isn't a deal breaker by any means, as in the video you can see coming at the buttons from the left as opposed to the right 'resolves' the issue as the button just get push further under your mouse pointer.
