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
  1. Render a component with ellipsizeMode='tail', numberOfLines={5}, and a fixed width.

  2. 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
    Asdasd alskd askd krgpwpr woertjfg dv,neo odl sdflkpwe sdkflpwle kdmkm welr
    sdkfm ksmd k d fmd df d fd fd fd f df d f df d f df df
    SASAD
    sdas

  3. 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
