Hiding the toolbar while scrolling causes the webpage to load incompletely.

I am using Firefox for Android, version 150.3. I have found that enabling the 'Hide toolbar when scrolling' option in settings causes search result pages to load incompletely. I have tried searching for other content to confirm whether this is a bug. I will use a search for 'bbc news' as an example to illustrate the issue. When 'Hide toolbar when scrolling' is turned on, the webpage fails to load all the way to the bottom. Only when I turn off this feature does the page load properly. I have made a screen recording video to show the specific issue. Since the feedback page does not support video uploads, please contact me via email: [edited email from public community support forum]. Additionally, I hope the feedback page can support Chinese, as I currently have to rely on translation to report this issue.
