[BUG] Collapsed paste strips out $'

What's Wrong?

When doing many line pastes into Claude Code, the symbols $' are lost. As an example, when pasting in a powershell script
$objectFileName = $metaFile.Name -replace '\.meta$', ''

Claude only gets this,

$objectFileName = $metaFile.Name -replace '\.meta, ''

This only happens when you paste in enough lines that the text box collapses the paste into [Pasted text #1 +108 lines]

What Should Happen?

Pasted code should have all characters sent.
