Mouse wheel on dropdown input triggers history clear confirmation

[rakunavi]

Hello all,

Many fields, such as search term input field, can display history via dropdown lists. Typically, a “Clear” option is provided at the end of the dropdown list. When you hover the mouse cursor over the field and scroll down with the mouse wheel to reach the end of the list, a confirmation dialog box suddenly appears asking for permission to execute “Clear History”.

However, for users, the act of reviewing a field's input history and the act of clearing all history are clearly different in terms of their importance and use cases. When scrolling the mouse wheel up or down, most users should only expect the input history to appear.

When using the mouse wheel to navigate dropdown lists, it's common to scroll a bit more than necessary and then scroll back just a little bit. In such cases, when the user happens to scroll to the end of the dropdown list, a UI that suddenly displays a confirmation dialog to clear the history seems unsuitable for general users.

In the following verification video, first click the dropdown arrow in the search term input field of the Search pane to view the current history items. After closing the list, scrolling down several times with the mouse wheel suddenly triggers the history clearing confirmation dialog to appear.

Since “Clear” isn't a frequently used function, it should only be accessible when the user explicitly clicks the dropdown arrow with the mouse to open the list and then selects it. This is similar to what was mentioned regarding wheel operations in zoom% text box. If it's technically feasible to implement this for dropdown lists in zoom% text box, it might also be possible to implement it such that only access to history items is allowed during wheel operations, without executing the “Clear” command.

Thank you for taking the time to read this message.

Best regards,

Hello, rakunavi

Thank you for the report, I have reproduced the issue and passed this along to the Dev team. I don't believe this was an intentional feature, so I expect it will be handled as desired.

Kind regards,
