Picker is broken by quotation mark in attribute

[gwarser]

Prerequisites

• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
• The issue is not present after wholly disabling uBlock Origin ("uBO") in the browser
• I checked the documentation to understand that the issue I report is not a normal behavior

I tried to reproduce the issue when...

• uBO is the only extension
• using a new, unmodified browser profile

Description

Selecting some cosmetic candidates does not have any effect. (all pointing to or inside the element with malformed attribute)

Picker throws exception when trying to querySelectorAll on attribute with quotation mark in value.

A specific URL where the issue occurs

Steps to Reproduce

1. open webpage
2. pick green download button
3. try selecting first two cosmetic candidates

Code sample:

<a href="src=&quot;https://propu.sh/pfe/current/tag.min.js?z=3453923&quot;">

<img data-original-height="640" data-original-width="240" src="https://1.bp.blogspot.com/-XRZH0MdSnK4/XxQfrtsDfjI/AAAAAAAAAKU/M9GUnb6IyBkeGXuvjFztmWeuZZn4Gts2wCLcBGAsYHQ/s320/download%2Bbuttons%2Bcolors.png" title="" style="" height="120" border="0">

</a>

Expected behavior

Selected filter should be chosen, visible in picker textarea.

Actual behavior

Previously selected filter is visible in textarea. (Network filter chosen automatically when picker is opened.)
