Cannot use # in message when requesting payment

[vromvonbeyond]

You can't execute a request link, if the issuer wrote an # inside the message field

For example this is the link from request above:
https://spark.iota.org/?address=THVGKOWZGHYDSAKZRCENIRMCEVFVOCODXFLJT9RNZXWYHLVATSOOSSMG9QMEABI9REIBUYOYM9ETYLJWDTCEMLEVIS&timeoutAt=1580417777&message=#IOTA%20&amount=1000000&receiver=Vrom

Only the wallet opens, but not on the page where you send money but only where your see your funds

It seems like the URL is being truncated after the # since # is usually used as a fragment identifier. Does it work if you replace the # with %23 so that it is escaped properly?
