Link display formatter breaks internal links with brackets in a query string

Using a link field with the 'Link' display formatter, internal links with a query string with brackets are broken.

Install Drupal
Add a link field to the article content type
Add an article with an internal link to a view with an exposed filter pre-set, e.g. /resources?tid_1[30]=30
Save and view the article
See the link is rendered as /resources?tid_1%5B0%5D=30&tid_1%5B1%5D=30, which does not work
Update the display to use 'Separate link and text'
View the article again
See the link is rendered as /resources?tid_1%5B30%5D=30, which works

If the link is absolute rather than relative, it also works, e.g. https://google.com/resources?tid_1%5B30%5D=30
