Description

Describe the bug
When I use dia or daa (my configured commands to delete inner parameter and outer parameter respectively), after undoing those commands with u, I cannot use ia or aa to select parameter in the current buffer anymore. I have to open a new buffer for them to work again.

To Reproduce
Steps to reproduce the behavior:

Open a csharp file with configured treesitter and treesitter textobjects.
Trigger command to delete inner or outer parameter using @parameter text object.
Press u to undo the change.
Try to select another parameter, it will not work.

Expected behavior
@parameter TextObject should work regardless of whether or not I press u.

Research direction

The report names no source file or test; begin with the reproduction entry points dia/daa, undo with u, and selection with ia/aa in a C# buffer. Confirm that @parameter selection fails only after undo, then identify the affected text-object or parser state and add coverage showing selection still works after undo.
