Description
Type: Bug
When editing a file where tab completions are available, the completion suggestions appear correctly in both Insert and Normal Vim modes. However, pressing Tab to apply the selected completion only works in Insert mode. In Normal mode, pressing Tab does not apply the completion.
Current Workaround:
When in Normal mode, the user must first press "i" to enter Insert mode, then press Tab.
Expected Behavior:
Tab completion should work seamlessly in both Normal and Insert modes, like previously.
Extension version: 1.29.0
VS Code version: Code - Insiders 1.99.0-insider (Universal) (88c05937becd43f3bc9457b65f2185e4cdaeae6e, 2025-03-27T23:30:01.317Z)

Research direction
Reproduce the issue with VS Code Insiders 1.99.0 and Vim extension 1.29.0 by opening a file with available completions and testing Tab in Insert and Normal modes. Trace the extension's completion and Tab key handling; done when the selected completion applies in both modes without switching to Insert mode.
