@ryanml Logged this issue because brave/brave-core#957 was reverted. Also i think the PR originally was intended to have brave/brave-core#957 (review). Could we have a separate PR done for this issue and not club with other UI fixes.

If brave/brave-core#957 doesn't end up landing in 0.58.x, we definitely need to make sure that the "empty" space is fixed before we ship 0.58.x. Just looks very strange.

After talking to @NejcZdovc, we won't be including the custom amounts in 0.58.x but will have a simple PR that fixes the above UI issue. 👍
