In the Database Manager, when displaying data from a table, a "pages" element shows up on the bottom left of the screen. This allows you to navigate through the pages of selected data. However, the z-index of this element is not set, which means it shows up underneath the "menu" element on the left side, effectively making it unusable. It's a small CSS fix that would fix this.

Here's a screenshot to show you what I'm talking about.
