Some hover texts are wrapped too late making them cut off at edge of screen

The bug

While hover texts created using hoverEvent by /tellraw in chat or in written books are wrapped if necessary (unlike villager restock hover text (MC-75699) or item tooltips (MC-26757)), they are sometimes wrapped too late making the hover text box too large and resulting in it being cut off.

See Hover text cut off (1.16.2-rc1).mp4.

Reproduction steps

1. Use the following command

   /tellraw @s {"text":"hover hover hover hover hover hover hover hover","hoverEvent":{"action":"show_text","contents":{"text":"mm mm mmm mmm mmm mmmm mmmm mmmm mmmmm mmmmm mmmmm mmmmmm mmmmmm mmmmmm mmmmmmm mmmmmmm mmmmmmm mmmmmmmm mmmmmmmm mmmmmmmm"}}}
   

2. Hover near the middle of the screen over the text
3. Move your mouse slowly towards on of the horizontal edges of the screen
   The hover text is cut off

Note: You might have to adjust the GUI scale or change the window width to reproduce this issue.
