bug(mac): Symbol Replacement Problems with "Tab"

[dyacob]

Describe the bug

This is particular to macOS and Micorosft Word , the issue does not occur on Windows with MS Word.

At the start of a line, or following a "Tab", Keyman is failing to replace the initial character. The initial character will then appear alongside the modified character. To reproduce:

1. Open MS Word
2. Select the ግዕዝ (EMUFI) keyboard
3. Select the Ge'ez Manuscript Zemen font
4. At the start of a new line type 1, the Ethiopic ፩ will appear
5. Now type TAB a horizontal menu of items appears, but ፩ remains on screen to the left
6. Type a number to make a selection from the menu
7. The menu has gone away and the select appears alongside the initial ፩

The above may be repeated where step 4 begins following a TAB symbol.

Menus appear on screen in list within square brackets [ ] and an index number. Type the number that corresponds to the desired numeral form to select it. For example:
