Text input bug with Keyman SIL IPA keymap(works fine in other apps)

Steps to reproduce

On a macOS computer, install the Keyman app, and within that, download the IPA (SIL) keyboard and select that as the input method.

Then open a sandbox vault, paste in the following table (yes, I did try to reduce it but with very limited success):

| X |  |     |   |  |  |
| ------ | -------- | --- | ------ | ------ | ------- |
| m      | n        | ɲ   | ŋ      |        |         |
| pʰ p b | tʰ t d   | c ɟ | k kʰ g | q ɢ    | ʔ       |
| f v    |          | ç ʝ | x ɣ    | χ ʁ    | h       |
|        | s z ʃ  ʒ | ɕ ʑ |        |        |         |
|        | ɹ        | j   |        |        |         |
|        | r        |     |        | ʀ      |         |
|        | l        | ʎ   |        |        |         |

Then, type type the following sequence of characters on your keyboard: iu=.

Did you follow the troubleshooting guide? [Y/N]

Yes

Expected result

When you press the =, you should see iu turn into .
This is what happens in other apps—I tried Firefox, Notion, and Notes.

Actual result

Instead, it becomes .

Additional information

A similar thing occurs with ai=, which should be but instead becomes .

This is beyond what we support.
