[BUG] URL parameter doesn't work on createTab Command. Especially '='.

I tried the code below.
Because I think '=' is recognized as positon option.
But it doesn't work.
```
map zC createTab https://chatgpt.com/?temporary-chat=true position=after
```
The URL of created new tab is "https://chatgpt.com/?temporary-chat".

version: 2.3.1

(I'm Japanese so sorry for not good at English)
