1886748 - Content at very bottom of webpages obstructed behind Android navigation bar

Status: RESOLVED DUPLICATE of bug 1885095

(Focus :: General, defect)

Description

[Rachel]

Attachment: expected vs actual behaviour.png

User Agent: Mozilla/5.0 (Android 13; Mobile; rv:123.0) Gecko/123.0 Firefox/123.0

Steps to reproduce:

• Installed Firefox Focus from google play.
• Navigated to https://support.mozilla.org/en-US/kb/file-bug-report-or-feature-request-mozilla (happens on pretty much any website tbf)
• Scrolled down to the very bottom of the page (scrolled down until I was unable to scroll down any further).
• Screenshotted results
• Did the same thing on Firefox Android for sake of comparison

Actual results:

See the right side of 'expected vs actual behaviour.png' (attached)

Upon scrolling all the way down (unable to scroll down further), the content at the very bottom of the page is hidden behind the Android system UI navigation bar thing(?).

It appears that the component(? idk the terminology) responsible for rendering web content in Firefox Focus stretches down to the very bottom of the phone's physical screen, instead of stopping at the top of the system UI navigation bar, meaning that the content at the very bottom of the page gets obstructed by this bit of system UI. And, of course, I can't scroll down further, because as far as the web component(?) is concerned, it has scrolled down all the way and the content at the very bottom is visible - despite Android's system UI covering the content at the very bottom.

Expected results:

See the left side of 'expected vs actual behaviour.png' (attached)

The content at the very bottom of a website MUST be visible upon scrolling down all the way - and MUST NOT be obstructed by the Android system UI.

In other words, the bottom of the web rendering component(?) MUST NOT extend further down than the top of the Android system navigation bar UI.

Firefox Android does not suffer from this problem, perfectly demonstrating the expected behaviour in this scenario (as one can scroll down all the way to the bottom of a webpage and see the content at the very bottom of the page, without the system UI obstructing this content).
