Deleting search terms is not possible with "x" button

[armhub]

How to reproduce:

1. Enter any search terms in the email search field
2. Click the "x" button to delete the search terms.
   -> The search terms are not removed from the search field.

Reproduced in Linux desktop client v218.240219.0

Test notes:

On any platform

• Pressing the 'X' button that appears after entering text into the email search text field clears the text field

There is a fix for this inside #6631.
