Unplayable gif output by VHS

[CodesOfRishi]

Describe the bug

Unplayable gif output by VHS. The .mp4 output works as expected but not the .gif output. A gif is created but it's unplayable.

Setup

• OS: LinuxLite
• Shell: Bash
• Terminal Emulator: xfce4-terminal
• Terminal Multiplexer: None
• VHS Version: vhs version v0.8.0 (88e634f)

To Reproduce

Run the below code in your terminal.

vhs demo2.tape

Source Code

Below is the content of my demo2.tape file I am using to create the .gif output.

Output out.gif

Sleep 2
Backspace 41
Sleep 1

Sleep 2

Type `# As you go through XYZ, it will start recording your activities`
Sleep 2
Enter 1

Sleep 1
Type `# So, let's start with searching and navigating through the logs`
Sleep 3
Enter 1


Sleep 5

Expected behavior

VHS should be creating a .gif file that can be viewed in a browser.

Screenshots
