Syntax error when compiling filter with compact

[CX3201]

Error :
Syntax Error: Unexpected token, expected "," (60:140)
> 60 | _createElementVNode("span", null, _toDisplayString($props.param1r_f_ctx.formatparam1)) + "次阅读", 1 /* TEXT */),
Template code:
<span>{{ param1 | format }}次阅读</span>

The reason I found:
In the generated code, there is an extra parenthesis in the _toDisplayString call
The transformFilter only rewrite the content but keep the old ast.

Is it a bug？
