{} markdown image attributes aren't interpreted

[CTLarsen]

I am inserting markdown into a page and referencing an image this way (following the documentation):

https://confluence.atlassian.com/bitbucketserver/markdown-syntax-guide-776639995.html

which is referenced at the Confluence documentation page: https://confluence.atlassian.com/conf76/confluence-wiki-markup-1018768909.html

I enter this markup:

![Image title](/download/attachments/217294505/gitlab-deploy.png){width=200}

and what I see is the image followed by the text {width=200} which shows that Confluence doesn't understand the attributes in the curly braces.

What I would expect is to see the image but resized.
