Summary0002364: JavaScript-related lockup
DescriptionWith JavaScript enabled, attempting to view page https://www.fanfiction.net/stats/story_eyes.php when logged in to site causes desktop to lock up (pointer moves, nothing responds).

Steps To ReproduceUnfortunately I don't think this page can be accessed without a fanfiction.net account, but I can replicate the effect by trying to load a RISC OS 'full save' application back into the browser after a Netsurf quit and restart.
Simply running the saved HTML page alone with JavaScript enabled gives no problems.
(I don't actually understand this, since the saved app contains no scripts that I can see....)
Additional InformationZipped full save attached.

Iyonix Aria running RISC OS 5.20
TagsNo tags attached.
Fixed in CI build #3032
Reported in CI build #2998

I tried it just now, loading story_eyes.zip into #2999 with JS enabled. It isn't an infinite single-tasking loop, but it did take an extraordinarily long time to resume normal operation. But it did in the end return, and render a sensible-looking page.

I tried again with story_eyes.zip on version #3000 here, and after five minutes or so it still hadn't rendered. The log isn't very helpful as it simply appears to report that everything was fetched successfully: Log3.zip

Harriet: I just tried it again on the Iyonix, and it single tasked for 9 minutes 51 seconds (CI#3000). Your machine must be similar.

For an interesting comparison, the BBxM under the same conditions was back well within 4 minutes. Most curious.

Raw processing power evidently counts...

Same behaviour turns out to affect ANY page on this site that displays the 'collapsible' menu entries, which is a bit of a killer if you accidentally try to reply to an e-mail PM notification, etc.

this is the same root cause as bug 2366 so we will update that

Was about 4 minutes on BBxM with CI#3000, now down to 11 seconds under the same conditions with CI#3032.

Duplicate of 2366, now resolved.
