Attached file svg_scaling_error.pdf

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

Open a pdf file containing certain SVG objects with firefox build in pdf viewer.
Set zoom to 30% or lower.

Actual results:

Some SVG objects are being displayed much bigger than expected.

Expected results:

SVG scaling should not break.
In Firefox 83 scaling for those symbols worked fine.

The Bugbug bot thinks this bug should belong to the 'Firefox::PDF Viewer' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I was able to reproduce it on latest Nightly version 90.0a1 (2021-05-11) (64-bit), Beta 89.0b10, and Firefox Release 88.01 on Windows 10.
I'll change flags accordingly. The severity suggested is S3.

When I created svg_scaling_error.pdf, my intention was to help you solve the bug, but apparently what it did instead was to make you think this problem is not relevant. But it actually is, you can find it on websites.
