1440385 - Warning: "Removed unsafe attribute. Element: svg. Attribute: xmlns" when evaluating 'window' in the new console frontend

Status: RESOLVED WORKSFORME

(DevTools :: Console, defect)

Description

[Brian Grinstead [:bgrins]]

STR:
1. Open the browser console (with devtools.browserconsole.new-frontend-enabled=true)
2. Evaluate `window`

The evaluation works, but below the window object I see: "Removed unsafe attribute. Element: svg. Attribute: xmlns. react-dom.js:11623:4"

I see this on any object preview.  For example: `window.foo = {}` shows the warning as well. Maybe this has to do with the expander arrow.

yes, I removed every xmlns attributes from the reps.js bundle and I don't see warnings after that.
I'll file an issue on Reps to fix this.

Turns out those are needed when the svg is inlined in a non-HTML document, which is the case of the layout panel in the inspector, where Reps are used.

IMO, there shouldn't be a warning if removing the attribute prevents the element to work :/

Filed bug 1445258 to see if there's an issue on the platform side
