profile-level-id in answer is higher than which in offer

In matchCoders() of ortc.ts it will generate a profile-level-id for answer, and set it to sendingRtpParameters. But when generating answer, it use sendingRemoteRtpParameters as answer param, so the profile-level-id will not be set to answer.

		case 'video/h264':
		{
			const aPacketizationMode = aCodec.parameters['packetization-mode'] || 0;
			const bPacketizationMode = bCodec.parameters['packetization-mode'] || 0;

			if (aPacketizationMode !== bPacketizationMode)
				return false;

			// If strict matching check profile-level-id.
			if (strict)
			{
				if (!h264.isSameProfile(aCodec.parameters, bCodec.parameters))
					return false;

				let selectedProfileLevelId;

				try
				{
					selectedProfileLevelId =
						h264.generateProfileLevelIdForAnswer(aCodec.parameters, bCodec.parameters);
				}
				catch (error)
				{
					return false;
				}

				if (modify)
				{
					if (selectedProfileLevelId)
						aCodec.parameters['profile-level-id'] = selectedProfileLevelId;
					else
						delete aCodec.parameters['profile-level-id'];
				}
			}

			break;
		}
