Bug 87194 – Some renderers in the Web Inspector interface have negative widths

• Status: NEW
• Component: Layout and Rendering

[Simon Fraser (smfr)]

Dumping the layer tree for some inspector content, I see:

      layer 0x112dc2a58 at (0,34) size 795x80 (composited, bounds=at (0,0) size 0x0, drawsContent=0, paints into ancestor=0)
        RenderBlock (positioned) 0x112dc2988 zI: 300 {DIV} at (0,0) size 795x80 class="resources-event-dividers"
      layer 0x112da6968 at (785,124) size -5x153
        RenderBlock (positioned) 0x112da6748 zI: 300 {DIV} at (0,0) size -5x153 class="resources-event-dividers"
      layer 0x112d9fbb8 at (-3,34) size 5x20 backgroundClip at (0,34) size 800x243 clip at (0,34) size 800x243 outlineClip at (0,34) size 800x243
        RenderBlock (positioned) 0x112d9fae8 zI: 500 {DIV} at (-3,0) size 5x20 [bgcolor=#999999] class="timeline-window-resizer"
      layer 0x11b30e1a8 at (797,34) size 5x20 backgroundClip at (0,34) size 800x243 clip at (0,34) size 800x243 outlineClip at (0,34) size 800x243
        RenderBlock (positioned) 0x112da01d8 zI: 500 {DIV} at (797,0) size 5x20 [bgcolor=#999999] class="timeline-window-resizer timeline-window-resizer-right"
      layer 0x112da7418 at (0,124) size 5x153

Note the "size -5x153" which means that a renderer got a negative width somehow. That should never happen.

This might not be relevant any more.
