Unregistered clicks on the menu sub-navigation items

[nilsmedina]

Describe the issue

I’m having a “ghost click” issue on the MC. Every time I use the sub-navigation in the left menu (hover and click on sub-item), the first click is not registered.

To Reproduce
Steps to reproduce the behavior:

1. Go to MC page (eg. Customers)
2. Navigate to a tab (eg. Customers > Custom fields)
3. Open left menu, hover an item and click on sub-item
4. First click is not registered

Seems like you need to interact with the page a bit before it happens, maybe it’s actually only when navigating to tabs.

Expected behavior

Every click registers and triggers the navigation.

Additional context

This has been happening for a while (multiple months). I thought it was on the shield team radar but realised it might not be.

Adding a bit more context:

• the bug is only happening when the menu is in collapsed state
• the bug is somehow related to / caused by the tabs
  • reloading the page when any tab-item is already active and clicking on a submenu item: works as expected
  • clicking on any tab-item followed by the submenu-click: doesn't work, first click is ignored
  • clicking on any tab-item, clicking on the background, followed by the submenu-click: works as expected
