Chrome version: 71.0.3578.89

Description:
There seems to be an issue with resizing Chrome interface for onscreen keyboard use. On some websites (dashboard.dittomusic.com as an example) you can't scroll to lower part of the page, which is covered with onscreen keyboard. It happens only before reboot, after reinstall/update.
So - 
If you remove Chrome and install it - issue is present.
If you reboot - issue is gone.
If you reinstall/update again - issue is back until reboot.


Steps to reproduce: 
1. Reinstall/update Chrome
2. Visit dashboard.dittomusic.com
3. Tap on username field to make onscreen keyboard appear
4. Try to scroll to the bottom of the page with keyboard still visible

Current Behavior / Reproduction: 
Lower parts of the page are not accessible

Expected Behavior: 
You could scroll to the bottom
