fix: Provide maximal asset list filter space

[darkwing]

Description

"All networks" is being ellipsized in the popup view. This maximum length is not useful; removing it makes it still ellipsize well.

Fixes:

Manual testing steps

1. Open the popup
2. See "All networks" text fully
3. Open the console elements panel and set an account name a mile long
4. See it ellipsize properly
