permissions_for returning wrong permissions

[Snawe]

Summary

permissions_for returning wrong permissions

Reproduction Steps

When you use channel.permissions_for, and you remove the "View Channel" permission, it still returns true.

NOTE:

• Code below works with v2.4.1
• But does not work with py-cord-dev-2.5.0rc5

Minimal Reproducible Code

I created a cog with:

    @slash_command()
    async def test_perm(self, ctx: discord.ApplicationContext):
        member = ctx.guild.get_member(self.bot.user.id)
        perm = ctx.channel.permissions_for(member)
        await ctx.response.send_message("🚫" if not perm.view_channel else "✅")

Expected Results

🚫if "View Channel" permission is denied. Else ✅

Actual Results

With py-cord-dev-2.5.0rc5: Always ✅
With py-cord 2.4.1: 🚫 or ✅, depending on the actual permission set

Intents

default

@Pycord-Development/contributors please work on this :)

Heyhey, after some consideration this will be held off until 2.6 as it's rather intricate. Instead of ctx.channel.permissions_for(member) (where member is the bot), you should use ctx.app_permissions.

Do you know if there's an alternative to interaction.app_permissions that does not require coming from a slash command event? I use permissions_for a lot so this is keeping me in 2.4

[NeloBlivion]

This issue only affects interactions; you can safely use permissions_for elsewhere

[NeloBlivion]

(To elaborate, the issue is specifically because we update permissions from interaction.channel incorrectly; you could circumvent this again by using bot.get_channel, assuming you haven't disabled cache)
