What does the yellow progress bar in stock browser means, while rendering downloading web page? While rendering / downloading web page the stock browser shows moving yellow progress bar. It tends to start increasing from the left, at times increasing from the right, there are also gaps in the yellow bar, before finally completing rendering / downloading and disappearing. I'd love to understand what it all means.

I've never seen it come from the right, nor have I seen it "gap", but the progress bar is just that, it shows the download progress for the page that you about to view.

After you posted your screenshot and video, it looks like that the browser is seeing that you are on the Malaysian version of Google. If I am correct, the Malaysian is read from Right to Left, which would be why the progress bar loads from right to left. 

If you just go to Google.com, it will load from left to right, or you have the default language on your device to be Malaysian, in which case, would default it to right to left.
