Reader mode, SVG and use elements


(Toolkit :: Reader Mode, defect, P3)

60 Branch





(Reporter: peter, Unassigned)




(Whiteboard: [reader-mode-readability-algorithm])

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180517114003

Steps to reproduce:

Spin-off from

Reader mode (perhaps only sometimes) removes the target of a use element's href attribute. Reader mode (sometimes) also strips the href attribute from the use element (though in the example below it does not - see the other bug for an example.)

1. Visit
2. Switch to reader mode

Actual results:

The SVG containing the <defs> is removed, making the use element fizzle, breaking the SVG content.

Expected results:

The SVG content should display correctly.

Thanks for the bug report and the test case! This seems like a P3 to me.
