We need to oversize the buffer and then fail to format. Use an

Need to have a function taking a const CFX_RetainPtr<X>& reference
as an argument, assign a different object to a m_ variable of the same
type in the function, continue to use the reference after the assignment,
and call the function elsewhere with the same m_ variable as the argument
while having no other RetainPtrs to the object.
Unclear if it is called in this manner, but the first three points
hold, so be proactive.

The crash on the new tab page is triggered by processing a transparency.
This creates a new Skia device in CPDF_RenderStatus::LoadSMask():
// cpdf_renderstatus.cpp # 2557
if (!bitmap_device.Create(width, height, format, nullptr))
which sets the Skia clip stack to empty.
It then calls
RenderObjectList()
RenderSingleObject()
ProcessClipPath()
which resets the clip stack;
// cpdf_renderstatus.cpp # 1882
m_LastClipPath = ClipPath;
m_pDevice->RestoreState(true);
At this point m_LastClipPath contains {m_Ref={m_pObject={m_pObj=empty } } }
The impelemntation in CFX_AggDeviceDriver::RestoreState() is
// fx_agg_driver.cpp # 1283
if (m_StateStack.empty())
return;
This hides unbalanced save/restores, but reworking PDFium to balance is nontrivial.
