I’m submitting a … (check one with “x”) [x] bug report [ ] feature request

Current behavior:

The input cursor is out of place, freezing, jiggering and overlapping with header while scrolling. See this video for the issue in action.

Expected behavior:

For the input cursor to behave normally.

Steps to reproduce:

Related code: Here is the reproducible repo. This repo is just a sidemenu starting project with inputs copied form the Input’s official doc

More Info: The input cursor issue is also present in emulators as well. Moreover, the IOS emulators(tried many) won’t show keyboard again after closing it once but this keyboard issue is not present in the device.
