In Chinese, we usually read out a date with year first, month latter and days after it. For example, if it's 4/6/1989 , we would say 一九八九年六月四日 (year 1989, June, day 4). I think there's not any relation with date format we use.
I know these two environment, and it helps with webpage scrolling only. In some menu, like history menu, it does not scroll but drag the text only. Better file a bug report.
Also, firefox does not recognize my touchscreen input in a few area. For example, you can not scroll on menu, history, and I am considering to file a report. Does this happen to you? Using Firefox on Wayland.
