If you have a good number of tabs they will be narrow enough you can't see the page loading indicator in the tab and there's absolutely nothing in a browser page to indicate it is currently reloading. Is there something to make it better visible?

I usually have very narrow tabs. The top left corner of my Chrome browser screen looks like this:
When I reload a page, the circular arrow symbol changes to an "X" until the reload has finished.
(If it is taking too long, clicking the "X" cancels the reload request.)
