my custom barrage control and problems about fullscreen button

[jlj001031]

Hello
I have inserted a custom barrage input box in the control bar and placed a barrage display layer above the video screen. Under normal circumstances, everything works fine, but when switching to fullscreen, the barrage layer gets hidden. After some research, I found that calling requestFullscreen on the parent div can make both the video screen and barrage layer fullscreen simultaneously. However, I am unable to prevent the default behavior of the fullscreen button. Could you please let me know how to stop the default fullscreen button click event and support a custom click method? Alternatively, could you consider adding the functionality for barrage input and display in future releases?
Thank you! Thank you! Thank you!
