Populated "partial" fields disappear when changing focus off the main form

[davewallace]

Describe the bug
After completing "partial" input textareas, and focussing off the main form, the textareas disappear from screen. They must still be there, because I can change my answer to anything else, then re-select "partial", and the textarea re-renders again, thankfully still containing my input. This is pretty annoying as it seems broken but also a means for incorrect info to be submitted (I typically write, then review, then submit), until I figured out I could re-toggle the partial fields, I thought my original entries were locked in (typos and all).

To Reproduce
Steps to reproduce the behavior:

1. Answer any question with a "partial" answer
2. Observe the textarea render, for user entry
3. Type something in the textarea
4. Change focus off the form (click the main page, for example)
5. Observe the partial textarea disappears
6. Change your answer to "Yes" and then back to "Partial", observe the textarea with your original input re-renders

Expected behavior
Textareas should remain on screen the whole time they're rendered based on the partial answer.

Screenshots
Screen recording attached, showing the issue on a pre-populated form, it happens on a fresh form too though.
