Spyglass and Render distance issues on Realms

Render distance issues on realms are not a new issue, but the Spyglass could be a fair stopgap solution. Essentially, I'd like very much for the Spyglass to expand the visible render distance.

As is, looking for end cities on a realms server is nearly impossible, but if the Spyglass could somehow make normally unloaded chunks visible, this would be essentially solved.

If the maximum distance a telescope can see on a realm is the realms default render distance, I don't think the telescope will even have much purpose in realms, or low render distance worlds anyway.
