incorrect tip banner text for tipping an image/video

[LaurenWags]

Description

Per spec, when tipping a tweet without any extractable text, you should see something like the image below, however, that's not what's occurring.

Steps to Reproduce

1. Locate a tweet with just an image (can use this one if needed, should work for both staging and prod: https://twitter.com/bravelaurenwags/status/1131664248856354816)
2. Click on Tip button

Actual result:

Expected result:

Expecting to see text that said 'Tip @bravelaurenwags for their tweet!' instead of empty tweet box.

This is what we it would look like now:

@NejcZdovc to confirm, even if the twitter user you're trying to tip has a custom banner, in this case you still want it to show the default text? Here's what I'm doing:
(using staging)

1. Navigate to https://twitter.com/bravelaurenwags/status/1131664248856354816
2. Click on in-line tip button
3. See this banner - note, it shows default text in the body (text from Update default tipping banner text #4616)
   
4. Close banner, navigate to just twitter.com/bravelaurenwags
5. Click on panel, click on Send a Tip
6. Here, the entire custom banner is shown, even custom text in the body of the banner:
   

Just want to confirm we are expecting different body text in the two places when tipping an image/gif.

title is different yes if you tip from inline tip or from panel tip
