[UWP] Input Field/TMP display text isn't properly updated during IME composition

How to reproduce:
1. Open the attached " TMPBug.zip" project
2. Open the "SampleScene2" scene
3. Build to UWP
4. Open built the solution in Visual Studio
5. Add the "Chinese (Simplified, China) Microsoft Pinyin" keyboard in Settings on the HoloLens 2
6. Start Debugging on Remote Machine (Debug and ARM64)
7. Click on the "TMP input field" field
8. Switch to the Chinese keyboard
9. Make sure the lower left side of the keyboard shows "中" instead of "英"
10. Type "zhong" on the keyboard

Actual result: Only the last character typed is shown (the string shown in the input field is z -> h -> o -> n -> g).
Expected result: All typed characters are shown ( z -> zh -> zho -> zhon -> zhong)

Reproducible with: 2019.4.18f1 (2.1.1), 2020.2.2f1 (3.0.1), 2021.1.2f1 (3.0.1), 2021.2.0a2 (3.0.3)

Notes:
- Not able to reproduce on 2018.4, because of project breaking

UPDATE:

This applies to all UWP and not just HoloLens and impacts both uGUI's InputField in addition to TMP.
Updating the bug accordingly.

    Resolution Note (fix version 2019.4):

    This specific issue is fixed on the platform side, but it may expose additional issues within TextMeshPro on HoloLens.
    To fully work properly, need to use an updated TMP package which contains extra fixes (once it becomes available):

    2019 LTS -> TMP version 2.1.5
    2020+ -> TMP version 3.0.5
