There is significant footprint and max memory usage increase in build 8.0-controls-scrum-h138.
For example footprint of NodeMemory.Buttons was increased by 27%:
 #137: 5,100 objects
 #138: 3,700 objects -27% (-1,400.00)

This also reduced runtime performance of some benchmarks.

I have created heap dump files for 1000 Buttons for builds 137 and 138. Here is the list of additional objects
which are created in case build 138 is used:

Build 8.0-controls-scrum-h138 contains the following changes:
    1. branch merge (detail)
    2. RT-26554: if an inline style changes, clear the style cache so new styles will be recalculated. (detail)
    3. Fixed RT-23878: -fx-ellipsis-string doesn't apply after setStyle (detail)


To reproduce the issue run for example NodeMemory.Button:
> cd JFX_WS/tests/performance/NodeMemory
> ant
> java -Xms64m -Xmx64m -cp "JFX_HOME/rt/lib/jfxrt.jar;./dist/NodeMemory.jar"
  nodememory.NodeMemoryTest -shape button -render true -allocMax 1000

to create heap dump file run with additional argument "-sleep true" and then use jmap to create heap dump file.
