1407012 - The Reload button can get unclickable if a page load is interrupted very early

Status: NEW

(Firefox :: Toolbars and Customization, defect, P5)

Description

[Itiel]

Environment:
Windows 10
Latest Nightly

STR:
1. Open the sidebar > History or Bookmarks
2. Right click any item > Open in New Tab (or Ctrl+click the item)
3. Immediately and quickly after step 2, press Esc in the keyboard to abort the page load

AR:
The Reload button in that new tab is not clickable. Reloading the page is not possible (F5 and Ctrl+F5 don't work either), only by focusing the URL and pressing enter.

ER:
The Reload button should be clickable also in this case.

I'm seeing this usually when my PC is under heavy load (where the tab's initialization takes time), but I can reproduce this issue easily whenever I want using the STR above, if done quickly enough.

Then this isn't a toolbar button bug, but caused by something else.

You marked this as a regression - can you find a regression window?

Interesting. I was sure this is a regression as it started on my Nightly just recently.
With mozregression I got as far as october 2008 (and stopped there) and it's still reproducible.
Removing the regression keywords.

This makes me wonder- could this possibly be the intended behaviour?

Marking P5 priority since this has existed since at least October 2008.
