Link URL text appears on DSB instead of above it

[BaccarWozat]

When hovering over a link, the URL text appears in the lower left corner. In the previous add-on I used to use (pre-Firefox 57), the text appears above the DSB, but now (with the current DSB) obscures it. Using Firefox 59.0.1 (64bit).

Which OS are you using?

This is what I see on Win10 + FF 59.0.2

I'm not sure how it would even be possible to cover that since it's probably part of the browser UI and DSB runs as inside of the webpage.
