* rendering/line/LineWidth.h:
(WebCore::LineWidth::logicalLeftOffset):
        
    Expose the left offset so we don't need to recompute it.

* rendering/SimpleLineLayout.cpp:
(WebCore::SimpleLineLayout::canUseFor):
(WebCore::SimpleLineLayout::computeLineLeft):
        
    Include the left offset from floats.

(WebCore::SimpleLineLayout::createTextRuns):
        
    Keep the flow height updated during the loop as LineWidth reads the current position from there.

* rendering/SimpleLineLayoutResolver.h:
(WebCore::SimpleLineLayout::RunResolver::Run::rect):
(WebCore::SimpleLineLayout::RunResolver::Run::baseline):
(WebCore::SimpleLineLayout::RunResolver::RunResolver):
(WebCore::SimpleLineLayout::RunResolver::lineIndexForHeight):
        
    We now bake the border and the padding to the line left offset. No need to add it during resolve.
