viewinvoice (html) dropdown

[int]

Just upgraded to WHMCS 7.6. In the 'viewinvoice' drop-down for the payment gateways, once a new payment method is selected (on the HTML invoice), the buttons underneath the gatewaydropdown change to the appropriate gateway buttons (as soon as you click out of the gateway dropdown box). However, the dropdown box itself defaults back to the first gateway option. 

I was told by WHMCS support that this issue was template specific, and that they couldn't reproduce it, but I just switched my WHMCS template to the default 'six' one, and the issue still occurs. All my other files are up to date, so I'm not sure what could be causing this? Please advise if you guys are seeing the same thing on your installations.

The behavior can be super confusing to users

@int are you using a customised Cart Template or Standard_Cart?

Do you see any error in Console when clicking the arrow? https://developers.google.com/web/tools/chrome-devtools/console/

Was using a customized cart template, but tried standard_cart and had the exact same issue.

 

Finally got an error just now in the console (wasn't showing up earlier):

content.js:43 [Violation] Added non-passive event listener to a scroll-blocking 'mousewheel' event. Consider marking event handler as 'passive' to make the page more responsive. See https://www.chromestatus.com/feature/5745543795965952

Is that bootstrap error helpful at all?

have you tried using both "Six" and "standard_cart" together - that would be the best test of the issue.

if it still fails when using them, then your best bet is to upload the 'vendor' folder again - this is not an issue that I can reproduce in my v7.6 dev.
