Search input field's clear button unclickable during first entry
In all Evolution's windows (mail, calendar, ...) there is a "Search:" input box at the top in which you can enter text. At the right end you can see the Clear button. Its popup hint is "Clear the current search parameters". The following can be reproduced without any account in Evolution.
On Fedora Workstation 36 with evolution-3.44.4-2.fc36.x86_64 and Fedora Workstation 38 with evolution-3.48.1-1.fc38.x86_64 you can enter text into the Search input box, but the Clear button cannot be clicked to clear current content. To make the Clear button operational, you must click outside of the Search input box.
