Fix Bugs With Multiple Highlight Providers

[thecoolwinter]

Description

Fixes a few issues when using multiple highlight providers.

• RangeStore did not clamp its output to only the requested range when querying for runs in a specific range. This broke an assumption by the styled store container, which broke the resulting highlighted ranges.
  • Adds some randomized testing to the query method to ensure that runtime contract is maintained.
• When reordering or adding new providers, their inferred priority would be lost.
