Multi document highlighting doesn't work with inline chat

[jrieken]

Testing #196342

• use the file below
• for the fib function ask copilot to use recursion
• select fib in RHS of the diff editor -> 🐛 no highlights in the outer editor
• the same happens when selecting fib in the outer editor

This repos independent of the editor.multiDocumentOccurrencesHighlight setting but it should work even without
