Since the last update, many SVGs are listed as 0x0 and don't generate correct previews in the interface despite working correctly previously.
An easy example of this is the charts generated by Google Data Studio, which can be tested against a public dashboard like this:
https://datastudio.google.com/u/0/reporting/1vqvDNQ1bqXhY5awvsW1OOQbjYpTliKAg/page/bnFIB?s=oh1ENMEdT04
In the previous version, output for the main line chart looked like this:
In the current version, it looks like this:
The preview isn't actually blank, but rather just getting the top-left of the chart which happens to be all transparent. This makes it impossible to know which chart you're downloading.
I'm guessing this is probably all related to invalid detection of the size, but definitely a regression from the previous behavior. I've seen this on other sites too, but I'm not sure what the commonality is related to sizing. As you test, you'll see that number of the other elements on the page preview and calculate sizes just fine.
(I was originally hoping to get the time to fix this myself, but it's been seeming like that isn't very realistic with my current work scheduleβso here's hoping someone else has the time!)
