api.AudioParam.linearRampToValueAtTime - works fine on Firefox, but listed as non-working

[parasti]

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

Been using linearRampToValueAtTime for a while on Firefox without issue, so I was surprised to see that the compatibility table says "Does not work".

What browsers does this problem apply to, if applicable?

Firefox

What did you expect to see?

Updated Firefox compatibility data.

Did you test this? If so, how?

We use it to fade background music in the game https://play.neverball.org (30MB automatic download, sorry)

You can also try it here https://mdn.github.io/webaudio-examples/audio-param/

@parasti Good catch, thank you, this was indeed fixed in Firefox 134 via https://bugzilla.mozilla.org/show_bug.cgi?id=1308435.

Would you like to open a PR to update the support data by adding version_removed: "134" to the current statement, making it an array, and adding a new statement with version_added: "134" without partial_implementation here:

browser-compat-data/api/AudioParam.json

Lines 276 to 280 in 182193b

	"firefox": {
	"version_added": "25",
	"partial_implementation": true,
	"notes": "Does not work (see [bug 1171438](https://bugzil.la/1171438) and [bug 1567777](https://bugzil.la/1567777))."
	},

(If you do, you could make the existing note a bit clearer specifying what didn't work. If I understand the issue correctly, the method linearRampToValueAtTime() existed, but it set the value without transition, is that it?)
