switching sheets produces unexpected auto height growing

Steps to Reproduce

1. import keikai-576.xlsx
2. select the 2nd blank sheet
3. select the 1st sheet

Current Result

• the 4th row becomes higher
  

Expected Result

row height should keep unchanged because B4:D4 is a merged cell, wrap text doesn't auto-adjust row height for a merged cell (compare with Excel)

Debug Information

• if you clear A4 content or style before doing the above steps, the issue doesn't happen
