Describe the bug
Crash panicked when handling json! with a line in the json that is too long (166 chars)

thread 'main' panicked at ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/ratatui-0.28.1/src/widgets/scrollbar.rs:570:10:
Scrollbar area is empty

To Reproduce

1. Create a request with a body !json
2. set the json value to have a line that is longer than 166 chars

• If you have slumber opened, just click your request in the scrollbar, go to it and it will crash
• if you didn't start slumber yet, it crashes on start
  ex that works:

body: !json
          {
            "one_very_lo_______________ng_keyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy": "{\"one_key_value_longgggggggg\":\"1234567891234567891234567891\"}"
          }

ex that crashed (1 extra char):

body: !json
          {
            "one_very_lo_______________ng_keyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy": "{\"one_key_value_longgggggggg\":\"12345678912345678912345678912\"}"
          }

I'll put out a release today with the fix version this. I noticed you're on 2.5.0, the new version will be 3.0.1 which will require a major upgrade for you. It should be painless though; patch notes for 3.0.0 are here
