Slide does not render >!spoiler text!< correctly in message preview

[bender-the-greatest]

Slide version: 6.7.1 Android version: 11

Slide renders [spoiler text[(/s) and [spoiler text](#s "displayed text") correctly in the message preview but this syntax does not render as intended on New Reddit once submitted, only Old Reddit.

Old Reddit, New Reddit, and Slide render >!spoiler text!< correctly once submitted but Slide does not mask the spoiler text in the message preview. This leads to confusion since it doesn't appear to work when previewing and in the case of some communities who are spoiler-sensitive this leads to backlash from other users or subreddit moderators because either you used the wrong spoiler syntax or you missed a typo because preview doesn't allow you to check your output correctly (>! spoiler text with wrapping spaces is an easy mistake to make !<). Checking the result on the main site outside of Slide isn't a reasonable solution since users are generally not going to check that their spoilers render on both versions of the site, especially while they are on mobile this is cumbersome to do.

I understand spoiler tagging isn't a standard feature of Reddit, but it seems Slide still accommodates this by rendering the [](/s) syntax correctly. I would ask that as >!spoiler text!< is also very popular that it also be rendered via Slide's submission preview.
