'options' argument in 'open browser' not honored when 'browser' argument is set to 'edge' or 'safari'

Problem statement:
Executing tests using Remote webdriver on BrowserStack but the options object passed under the 'options' parameter under the 'open browser' keyword doesn't get honored when the 'browser' parameter is set to 'edge' or 'safari'.

However, this works when the 'browser' argument is set to either 'chrome' or 'firefox'.

Note: The same also works across all browser argument values when using selenium 3.141.0 and desired_capabilities

Setup information:
python 3.7.12
robotframework 5.0.1
robotframework-seleniumlibrary 6.0.0
selenium 4.3.0

Steps to repro:

• Create the below-mentioned files:

test.robot

*** Settings ***
Library SeleniumLibrary
Library Collections
Library test.py

*** Variables ***
${test_url}= https://google.com
${USERNAME}= %{BROWSERSTACK_USERNAME}
${ACCESSKEY}= %{BROWSERSTACK_ACCESS_KEY}
${REMOTE_URL}= https://${USERNAME}:${ACCESSKEY}@hub-cloud.browserstack.com/wd/hub

*** Keywords ***
Open Session
${opts}= browserstack test
open browser remote_url=${REMOTE_URL} url=${test_url} options=${opts} browser=edge

*** Test Cases ***
Quick Test
Open Session
close browser

test.py

from selenium.webdriver.edge.options import Options

def browserstack_test():
edge_options = Options()

bstack_caps = {
    "os" : "Windows",
    "osVersion" : "8",
    "debug" : "true"
}

edge_options.set_capability("browserVersion", "90")
edge_options.set_capability("bstack:options", bstack_caps)
return edge_options

========================================

• Create a free account on BrowserStack
• Set the BrowserStack username and accesskey of the account under the following env variables on your machine:
  BROWSERSTACK_USERNAME
  BROWSERSTACK_ACCESS_KEY
• Run the test --> robot test.robot

You'll notice that the test runs on a random version of Edge and the 'options' argument doesn't seem to get honored at all.

Inizia dai file di riproduzione test.robot e test.py, quindi traccia il modo in cui la keyword open browser gestisce l'argomento options per i valori del browser edge e safari. Esegui robot test.robot con la configurazione Selenium e BrowserStack fornita e confronta le capabilities risultanti con quelle di chrome e firefox. Il lavoro è completato quando le opzioni vengono rispettate anche per edge e safari.
