iOS 26 Section Header Flickering During TableView Scroll

I'm adapting for iOS 26, and I found that when pressing and slowly swiping the screen, the section header near the bottom of the navigation bar in the tableview flickers frequently. How can I fix this issue?

Please view the video in the github project: issue.mp4

Has solved the problem, because in the tableview init estimatedSectionHeaderHeight = 0, but the actual tableview heightForHeaderInSection: set to 78;
