Reload button on the popup isn't disappearing on internal pages

[Mikey1993]

For example, when entering chrome://flags on Chrome, and changing a Dynamic Filtering rule, the reload button on the popup isn't dispappearing after clicking it (though it does reload the page).

• Note 1: On FF Nightly, tested with about:memory page - same results.
• Note 2: The Element Picker icon isn't shown on the popup for for that page, is this derived from the same origin in the code?

Element picker is not allowed to work on anything else than http/https web pages.

@gorhill @Mikey1993 the problem with chrome://flags and about:memory is that an actual net request never occurs for their mainframes.

As such, logRequest never gets called and the pageStore doesn't get a contentLastModified which is necessary for the reload button to go away in the popup.
