Reference field autocomplete dropdown options not highlighting on hover in PROD

[amcintyre]

Hello,

We are seeing an issue in our PROD instance where some reference field autocomplete dropdown options are not visually highlighting when hovering over them.

Example behavior:

When typing into a reference field, the autocomplete dropdown displays matching records. The values are still selectable, but when hovering over the dropdown choices, the row does not visually highlight.

A few details:

• This is only happening in PROD
• The same field works as expected in TEST and DEV
• The affected reference field configuration appears to match between PROD and TEST
• The lookup popup opened from the magnifying glass works normally
• It does not appear to affect every reference field
• We tested in InPrivate/Incognito and the issue still occurs
• We tested with another user and the issue still occurs

Has anyone seen this behavior before? Any suggestions on what to check next would be appreciated.

@ismaelwismann - Same thing on our end.

@NikethK We tested it on the Assignment Group and we are still experiencing the same issue.

I am not sure if this helps anyone. But I did see that there is a difference in the HTML layout of the assignment group (not working) and the assigned to (working) dropdowns. But I thought I will attach the screenshots anyways

I have identified the cause for the issue.
The HTML used to store the options for AJAXReferenceCompleter uses a <div>, while AJAXTableCompleter uses a <tr>.

But the CSS selector in css_includes_polarisberg.cssx used to do the highlighting is ".ac_dropdown tr[role=option].ac_highlight". So it doesn't target the <div>.

Are you aware if it’s fixed in any Zurich patches?
