[Steps to reproduce]:
Open the browser with the profile from prerequisites.
Drag the Sidebar border to the maximum right.
Copy a long string and paste it into the Search box.
Observe the way the string is displayed in the Search box.
[Expected result]:
The string is correctly pasted and visible in the Search box.
[Actual result]:
The string is visible only on the left side of the Search box, the other side that seems to be part of the extended Sidebar area doesn't display anything.
[Notes]:
This is also reproducible by manually writing a long string in the Search box.
