Steps to replicate the issue (include links if applicable):

• Open article, Shakti Kapoor
• Edit a section
• Click the image icon in the editing toolbar to Insert Media
• Try to click the X button
• Choose an image and click Next
• Add a caption
• Try to click "Insert"

What happens?:

• On the "insert media" screen, the close X does not work (similar to T372301), and the app must be force-closed to navigate away
• "Insert" does not work

What should have happened instead?:

• the Close X brings you back to the article's wikitext
• "Insert" adds the image's wikitext into the article

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
