Hi, I am having issues with the loading icon on the IndicatingAjaxButton and IndicatingAjaxLink. Previously I'm on Wicket 9.0.0-M4 and it was working fine. But after upgrading to Wicket 9.0.0-M5 (and later versions), I'm not able to see the loading icon any longer.
I checked further in the code that the AjaxIndicatorAppender now has the hidden attribute instead of the style=display:none. However, when I click the IndicatingAjaxButton, it will still append the style=display:inline as before (but due to the hidden attribute, the icon will not show). Is there anything else during the upgrade that I needed for the IndicatingAjaxButton (and link) to work? Please advise. Thank you. Regards. Michelle
