Search navigation doesn't scroll main panel
Description
When using the search feature and clicking the "next" arrow to navigate through the search results, I've noticed an issue. While the lower panel correctly updates to display the next search result's content, the main panel fails to scroll to the corresponding position of the search result in the list of messages. As a result, the user needs to manually scroll through the list to locate the newly displayed search result, which disrupts the workflow and can lead to confusion.
Expected Behavior
Upon clicking the "next" arrow in the search dialog, the main panel should automatically scroll to the position of the displayed search result in the list of messages.
Steps to Reproduce
- Open a po file in the translation editor.
- Enter a search query in the search dialog.
- Click the "next" arrow to navigate through the search results.
- Observe that the lower panel updates to show the next search result, but the main panel remains stationary.
