Using new line as blockEnd tag don’t work

[DevOpsCraftsman]

I’m trying to use a "blade" (from laravel) like syntaxe, but without success:

const nunjucks = require("nunjucks")
nunjucks.configure("", {
    tags: {
        blockStart: "@",
        blockEnd: "\n",
    }
})

nunjucks.renderString(`
@if 'a' == 'b'
  <p>Yes</p>
@endif
`)

Template render error: (unknown path) [Line 3, Column 12]
  unexpected token: /

And with:

nunjucks.renderString(`
@if 'a' == 'b'
  a
@endif
`)

Template render error: (unknown path) [Line 4, Column 1]
  expected block end in if statement

I think the parser can’t handle it properly for some reason…
