v0.7.2

[ra1028]

Fix

• The element updates are included in stage 1 changeset to fix the animation glitch occurs when element updated with other differences.
  The animation glitch when the difference contains section updates was fixed in Sectioned element updates are included in changeset stage 4. #10 , but another glitch occurred when element update was included.
  Although this is a workaround, the glitch of the latter is more likely to occur, so I fixed.
