Description Daniel Bates 2020-03-14 13:23:24 PDT
Steps to reproduce:

1. Run Tools/Scripts/debug-minibrowser --debug
2. Set breakpoint in LineLayout::canUseFor(): <https://trac.webkit.org/browser/trunk/Source/WebCore/layout/integration/LayoutIntegrationLineLayout.cpp?rev=258400#L69>
3. Tell lldb to run – to launch MiniBrowser
4. Disable Next-generation line layout integration (LFC) under Settings > Internal Features.
5. Visit attachment #393589 [details] (from bug #209112)

When breakpoint is hit, evaluate "RuntimeEnabledFeatures::sharedFeatures().layoutFormattingContextIntegrationEnabled()". It will return true. But it should be false.
