No popup for ANY image I mouseover

The commit: handle autoscaled SVG + code cosmetics (which was the 4th after the release of v1.1.3), has caused me the following:

from that point, there’s no popup with the full image for ANY image I mouseover anymore, the image zoom becomes displayed as NaN% at some point, but the accompanying text is displayed ok (but only that) on the upper part of the page, and pressing t (open in new tab) or d (download image) both still work ok.

Note: the version before that commit, i.e. https://github.com/tophf/mpiv/commit/174366ed6cc328564e3df7487f07a7562c02c62b works fine.

STR in a fresh Chrome profile with only Tampermonkey beta/Violentmonkey and the script of https://github.com/tophf/mpiv/commit/3e1ade87cd2c1450024fb099b2f5a81e9f34f052

• import my various rules (see below)
• go to e.g. https://www.instagram.com/instagram/
• hover any image. Notice the following:
  • the cursor spins forever as I mouseover any video thumbnail
  • there’s no popup (with the full image) for ANY image I mouseover,
  • the first time I mouseover any image, the accompanying text of the relevant post is displayed on top of the page ok (but there’s no zoom info, image dimensions or MP). If I mouseover again, then the zoom level is displayed as NaN% e.g.
  • pressing t (open in new tab) or d (download image) both still work ok.

The rules that I import, are too many to post them here, so, I attach them as text file: my rules.txt

Fixed now in MPIV.

The problem was exacerbated by the following rule:

{
  "r": "(.*\\.uvnimg\\.com/.*/)\\?url=(.*)",
  "s": "$2"
}

It should be "(\\.uvnimg\\.com/.*?/)\\?url=(.*)" or "(^.*?\\.uvnimg\\.com/.*?/)\\?url=(.*)"

You’re using an unnecessary .* in many of your rules, for example: .*\\.(jpe?|pn)g.* should be \\.(jpe?|pn)g because you’re not using those parts covered by .* anywhere. The “greedy” .* is a known cause for catastrophic backtracking so it may take minutes to resolve. If you absolutely have to use it, prefer its non-greedy version .*? or find about other ways to safeguard against catastrophic backtracking like positive/negative lookahead.
