potential defect for Pinyin input method.
This is about the input method for Pinyin - Simplified Chinese.
Issue: click on "笔画" in the bottom of the character selection popup area/list, the last line will show only half of the characters, please refer to the screenshot below.
This is happening if set the font size above 16, for example 18 will have this issue.
Steps to find this option: Settings --> Keyboard --> Text Input -->hit the Edit button, then select Pinyin - Simplified, change the font size.
I'm using the latest OS Sonoma 14.2.1
Hope this issue could be addressed.
