            Bug ID: 209113
           Summary: MiniBrowser does not respect changes to Internal
                    Features in Legacy WebKit window
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dbates at webkit.org
                CC: zalan at apple.com

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 (from bug #209112)

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