Main difference is that you're not explicitly setting the number of lines, but other than that I think it looks likely to be the same core issue. Going to close this as a dupe of the other, feel free to add more commentary in that one. The guess from that thread is that updating the Android Studio version will address this.

Its very similar if under hood there happens placeholder update after setting TextInput's value to empty string.
