Description
**Description:** Setting `app:hintEnabled="false"` properly hides the hint but keeps the top space where it would normally appear, causing misalignment of components.
**Expected behavior:**
The problem as seen in the Layout Inspector:
Marked is the mentioned claimed space.
Also from the IDE preview:
With `app:hintEnabled="false"`
Without `app:hintEnabled="false"`
The expected behavior would have been basically the second the "without" visuals but without the animation and the hint.
**Source code:**
```
```
**Android API version:** From 23 up to recent
**Material Library version:** 1.2.0-alpha5
**Device:** Emulators, Pixel 3XL, Pixel 4XL, Samsung S9, S10, others

Research direction
Start at the TextInputLayout entry point and reproduce the XML case with app:hintEnabled="false" and an error. Verify the layout in the Layout Inspector and IDE preview; done means the hidden hint no longer reserves top space while the error and TextInputEditText remain correctly positioned.
