Get Element States keyword in presenter mode

[tomeekCZ]

Describe the bug
When in presenter mode, the keyword Get Element States does not return state detached for element, which is detached. It will raise timeout error instead.

To Reproduce
Steps to reproduce the behavior:

*** Settings ***
Library     Browser    enable_presenter_mode=False


*** Test Cases ***
Test
    New Browser    headless=False
    New Page
    Go To    https://robotframework.org/
    ${state_visible_element}    Get Element States    //h1[@class='title']    evaluate    visible in value
    ${state_detached_element}    Get Element States    //h1[@class='wrong_title']    evaluate    detached in value

Expected behavior
When presenter mode is not active, the code works just fine. When I set presenter mode as active, the first Get Element State works (the element is there), but the second one doesn't. The element is not there, but it should return detached instead of the error message.

Desktop (please complete the following information):

• OS: Windows 10, build 19044.1706
• Browser: Chromium
• Version: 102.0.5005.40 (Developer Build) (64-bit)

The presenter mode actually modifies the HTML around the element. which may interface with detecting the correct element state. I think this is expected behavior and can not be fixed other than not using presenter mode.

Could it be that this is not expected behavior after all?

I've got keyword which uses Get Element States to get boolen value for hidden state (quite similar as example in Browser library keyword documentation) and it works just fine in presenter mode with Browser library v.12.1.0 but does not work with any later library versions.

@aaltat That is caused, because locator.hover() is called in presenter mode.
and because locator is not valid in case of detached, it fails with a timeout.

Maybe we can fix that by catching that locator.hover exception.

I would let it open for now.
It has to be analyzed.

@tomeekCZ : just as a remark: do not do xpaths like that: //h1[@class='title'] just use css h1.title. ;-)

Actually @aaltat that has happened here:

I will remove presenter mode from Get Element States again.

Will be fixed with #2109
