editor.action.showHover does not focus the hover when called programatically

[musjj]

Does this issue occur when all extensions are disabled?: Yes

• VS Code version: Code 1.88.1 (e170252, 2024-04-10T17:34:12.840Z)
• OS version: Linux x64 6.6.28

Steps to Reproduce:

1. Call vscode.commands.executeCommand('editor.action.showHover') twice from a plugin.

When called from a regular binding, this will focus the hover. When called from a plugin, this will just close and re-open the hover again.

For a real-world example, this is a problem for the Vim plugin: VSCodeVim/Vim#3740 (comment)

The relevant code:

src/actions/commands/actions.ts

@RegisterAction
class ActionTriggerHover extends BaseCommand {
  modes = [Mode.Normal];
  keys = ['g', 'h'];
  override runsOnceForEveryCursor() {
    return false;
  }

  public override async exec(position: Position, vimState: VimState): Promise<void> {
    await vscode.commands.executeCommand('editor.action.showHover');
  }
}
