Rename folder bug fix

[dogra25130]

Removed header height to zero code. When we were renaming a folder which will impact the first folder of in the sorted order, height of header was getting reduced to zero.

e.g. say we have two folders: Folder_1 : B Folder_2: C

Now if we rename Folder_2 to A, then height of header was getting reduced to zero which caused the issue.

Attaching a videos for the reference: Fixes: #1573
