Webview, startActionMode() is not called

问题

I need to have a customized text selection menu (CAB) in my Webview.
As this question is answered, I override startActionMode method, and it works fine

THE PROBLEM:

In some devices (two huawei devices as far as I tested) webview shows android default menu, and startActionMode method is not called at all.
I override other methods and the only method which gets called when I select some text is showContextMenu().

I considered using a JS solution for this case, but I prefer to solve the issue simpler and with a native solution.

Moreover when I override showContextMenu() method, I noticed the stack trace is different in devices which work fine and the ones not.

stack trace for devices work fine:
