Undo ignores last changes when cursor changes context

### Expected Behavior

After making a change, Command + Z (CTRL + Z) should undo any last update.

### Actual Behavior

When a change is made, if cursor is moved to any other textbox, undo action does nothing.

### Reproduction Steps

1. Create new HTTP request
2. Enter any text in request URL textbox
3. Click (focus cursor) on new parameter name textbox. No need to type anything
4. Click CTRL + Z and notice that nothing is happening

### Is there an existing issue for this?

- [X] I have searched the [issue tracker](https://www.github.com/Kong/insomnia/issues) for this problem.

### Additional Information

Undo action is expected to undo any change recently made in the editor / app. Current behavior may cause data to be lost, as more often then not some quick changes are done to requests which cannot be easily undone.

Reproduce the issue on Windows by editing the request URL, focusing the parameter name textbox, and pressing Ctrl+Z. Trace the undo handling across the request editor's textbox focus changes; done means the last URL edit is undone even after focus moves to another textbox.
