After becoming a v9.0 from v8.2, the height of the side by side fields location becomes misaligned when the character is entered in the input field of the record.

Basically, after entering a character, the height of the field is shifted down so that there will cause a gap on fields on the same height next to the section.
If there is a lookup field in the tab, there is also a case where the height of the input field shifted up before the character input.

Beacause the appearance is not good, it is much better to keep the side-by-side fields location same as with v8.2 on v9.1
