Paint bucket tool only fills visible area

Summary:

When creating a grid, one can fill the cells of the grid with the paint bucket tool. However, it only fills the visible area/px.

• When really zoomed in, where you can't see a complete cell, only the portion of the cell visible in the viewport is filled.
• When really zoomed out, the edges of the cell do not get filled.

Steps to reproduce:

• open Inkscape
• create new document
• go to extensions -> render -> grid -> grid -> apply
• select the paint bucket tool
• select a color that is not the background color nor grid color.
• zoom in so you are only seeing part of the cell
• click the cell to fill it.

What happened?

Only part of the cell was filled.

What should have happened?

The entire cell should have been filled.
