The issue is found on `enwiki beta` and might be specific to beta cluster env
**Steps to replicate the issue** :
* go to https://en.wikipedia.beta.wmcloud.org/wiki/Polar_bear?shareHighlight=1 (another example [[ https://en.wikipedia.beta.wmcloud.org/wiki/Brown_bear?shareHighlight=1 | Brown_bear ]])
* as the page loads, the Console immediately shows the following error:
```
TypeError: parsedUrl.resizeUrl is not a function
at getImageSrc (ShareQuoteDialog.vue:103:22)
at tV.eval [as fn] (ShareQuoteDialog.vue:116:13)
at eR (vue.js:5:8449)
at get value (vue.js:5:19431)

at rX (vue.js:5:56165)
at e.watch (vue.js:9:14814)
```
* the "Share quote" button appears - click on the button
**What happens?**:
- the "Share quote" button disappears without showing the Share card
**What should have happened instead?**:
- fix the error so that the dialog is able to load as intended, or
- automatically close the share dialog if the error is not fixable/recoverable
NOTE: there are articles that have no problems displaying a share card with images, e.g. [[ https://en.wikipedia.beta.wmcloud.org/wiki/Antarctica?shareHighlight=1 | Antarctica ]]
