ReplaceTab attribute causes binding and manual event to malfunction - no update on delete

[bjh0]

Describe the bug
When using a MemoEdit component, you can use a two-way binding or a manual event binding - as per the documentation. But if you add the ReplaceTab attribute the binding and/or manual event malfunctions. Adding text still works as normal, but deleting text no longer triggers a binding update.

To Reproduce
Steps to reproduce the behavior:

1. Clone the sample repo here: sample repo
2. Run the project and land on index page
3. There are two memo components that work - one uses two way binding, the other uses an event.
4. There are another two memo components that only update when text is added, not deleted. Only difference is the ReplaceTab attribute was used.
