selenium: Timeout set to 10 minutes, but timing out after 3 minutes

🐛 Bug Report

I am setting the timeout to 10 minutes because I am using https://github.com/scrapinghub/crawlera-headless-proxy

I am seeing it timeout after 3 minutes (still downloading all of the JS/CSS files)

To Reproduce

Set page load timeout to 10 minutes

Expected behavior

Expecting it to timeout after 10 minutes, not 3.

Test script or set of commands reproducing this issue

driver.manage().timeouts().pageLoadTimeout(Duration.ofMillis(600000));
driver.manage().timeouts().setScriptTimeout(Duration.ofMillis(600000));

try {
driver.get(uRL.toExternalForm());
} catch (TimeoutException te2) {
log.warn("Chrome Driver thread timed out: " + uRL.toExternalForm());
}
