Corner rendered incorrectly in figure

[7Z0t99]

Link to PDF file: http://mirrors.ctan.org/graphics/pgf/contrib/circuitikz/doc/circuitikzmanual.pdf (version 1.1.2)

Configuration:

• Web browser and its version: Firefox 77.0.1
• Operating system and its version: Windows 10 1909
• PDF.js version: 2.5.95 (included in Firefox)

Consider the bottom left corner in the figure at the bottom of page 148.

What is the expected behavior?

What went wrong?

This is somehow related to a rectangle having a zero width.

It's because of:
https://github.com/mozilla/pdf.js/blob/master/src/display/canvas.js#L1189
The pdf docs:
https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#page=141
don't mention that neither width nor height for a rectangle has a minimal value.
The rendering in evince is correct and the code in poopler doesn't use a minimal width:

Unfortunately, I'm not able to get the pdf in #4260 (comment) so I can't check what's wrong exactly with it.
Anyway I think that removing these "default" values will fix the issue.

@Snuffleupagus might also still have that PDF?
