Redmine

The autocomplete request succeeds, but its suggestion popup is often not displayed when the browser page zoom is not 100%.

At 100% page zoom, autocomplete works normally. When browser zoom is changed, the issue occurs across multiple browsers:

• Chrome: 110% — the popup is not displayed most of the time
• Microsoft Edge: 110% — the popup is not displayed most of the time
• Firefox: 120% — the popup is not displayed most of the time

Windows display scaling is 100%.

Resizing the browser window sometimes makes the popup appear again. Opening DevTools while docked also sometimes makes it appear, presumably because it changes the page viewport. However, DevTools in a separate window does not resolve the issue.

In the Network panel, the autocomplete request is sent and receives a response even when the popup is not visible.

Redmine version: 6.1.3
Theme: Default
Plugins: Redmine Checklists plugin (Light version)

Expected result:
The autocomplete suggestions popup should be displayed reliably regardless of browser page zoom level.

Actual result:
The autocomplete suggestions popup is often not shown at non-100% browser page zoom, despite the request receiving a response.
