Describe the bug
Word Online in Chrome and Safari will not replace context correctly at the beginning of a paragraph. It does however work correctly elsewhere in the paragraph. This may be a race condition (in Safari there is some unreliability elsewhere in the paragraph also).

This issue does not arise with Firefox. In Firefox, Word Online appears to work 100% correctly.

To Reproduce
Steps to reproduce the behavior:

1. Open office.com and start a new document
2. With the GFF Amharic keyboard, type ta
3. The document is left blank, on Chrome. On Safari, ትታ is the result.

Expected behavior
The initial ት letter should be converted to ታ.
