When switching from a scheduler page with data and row headers, to a scheduler page without data, the newly available space is added as a grey area at the end of the timeheaderrow.
This issue interrupts the users experience.
To comprehend this issue, i`ve created this codepen: https://codepen.io/TORISO/pen/GRNYqWL?editors=1011
For simplicity there a only data displayed for March 2021. By switching to the next page, you see the issue. Notice that when pressing Next twice, the width calculation of timeHeaderRow is correct.
Thank you for your efforts!
