Sergio, could you please update Component when you assigning the bug. Thanks!

michaeldo@ any update here?

Looks like michaeldo@ started working on this already: http://crrev/c/579585/
Changing Status.

Sorry, pkl is right, I had started but forgot to update here.

As can be seen in the first upload on that CL, originally I tried to fix this by updating the timeout, however that would make the failure rate in crbug.com/542933 worse by shortening the time Chrome has to fetch the element details from the DOM.

eugenebut@ and I talked about our options and the new patch (on the same CL) actually waits for the DOM element details so we can use whatever long press duration we want.

The side effect (which we believe is a positive one) is that the WKWebView "Safari" context menu will never be shown. Right now it is shown if we can't fetch the details fast enough and it is shown if you long press on context inside of an iframe.

Adding mardini@ to review the last point where behavior changes slightly.

This change in behaviour sounds fine to me. It's better than show two context menus. Also, just to confirm, these changes apply only to links, correct? Long-pressing regular text would still select it and show [Copy | Look Up | Share]. 

Adding Pink as FYI.

Sorry for the back and forth, but Eugene pointed me to an old hack that will let us fix this in a simpler way without changing the behavior of the menu.

(I still plan to change the behavior in a separate CL in order to reduce the failure rate of the existing context menu and in order to prevent the default WKWebView context menu from showing, but it hopefully won't need to be merged to fix this RBS.)

FYI, with these steps to reproduce only System Context Menu show up:
  1. Launch app
  2. Navigate to the Google.com 
  3. Search for images
  4. Tap on any images tab 
  5. Long Tap on any images 
  6. Tap on Share Mail or Share Notepad
