Bug 98026 – Assertion triggered in WebCore::RenderTextControlSingleLine::layout when running fast/dom/shadow/input-with-validation.html

• Status: RESOLVED
• Resolution: FIXED
• Component: WebCore Misc.

When running fast/dom/shadow/input-with-validation.html  in content shell:

echo file://$(pwd)/LayoutTests/fast/dom/shadow/input-with-validation.html | out/Debug/content_shell --dump-render-tree --no-sandbox

I trip the following assertion (or crash in a release build)

ASSERTION FAILED: innerTextRenderer

Dimitri, any idea what's going on here? innerTextRenderer is a shadow DOM thing, isn't it?
