调研方向
未指定源文件或测试。首先使用 React Native Windows 的 Text 组件，通过 ellipsizeMode='tail'、numberOfLines={5}、固定宽度以及提供的包含长单词的文本来复现该问题。完成标准是文本使用所有允许的行数，并且省略号出现在最后一行的末尾。

描述
Problem Description
ellipsizeMode='tail' with numberOfLines truncates at a long-word boundary instead of at the end of the last allowed line.
When text contains a word longer than the line width, the ellipsis fires on line 2 as soon as that word overflow without firing at the actual last line allowed
Actual output (numberOfLines={5}):
Line 1: hree words eheh
Line 2: VeryloooooooooooooooooooooooongWoooooooo...
Line 3: Asdasd alskd askd krgpwpr woertjfg dv,neo odl sdflkpwe sdkflpwle kdmkm welr
Line 4: sdkflpwle kdmkm welr sdkfm ksmd k d fmd df d fd fd fd f
Line 5: df d f df d f df df
Expected output:
Line 1: VeryloooooooooooooooooooooooongWoooooooo
Line 2: oooooooooorddddddddddddddasdasdwasd
Line 3: Asdasd alskd askd krgpwpr woertjfg dv,neo odl sdflkpwe sdkflpwle kdmkm welr
Line 4: sdkflpwle kdmkm welr sdkfm ksmd k d fmd df d fd fd fd f
Line 5: df d f df d f df df...
Steps To Reproduce
-
Render a component with ellipsizeMode='tail', numberOfLines={5}, and a fixed width.
-
Set the text content to a string whose first word is longer than the component width,
followed by several shorter words:<Text
ellipsizeMode='tail'
numberOfLines={5}
style={{ width: 200 }}>
VeryloooooooooooooooooooooooongWoooooooooooooooooorddddddddddddddasdasdwasd

sdkfm ksmd k d fmd df d fd fd fd f df d f df d f df df

sdas -
Observe that the ellipsis appears at the end of the long word on line 1,
while the remaining lines are unused.
Expected Results
The text should fill all numberOfLines lines before truncating.
The ellipsis should appear at the end of the last line
