Element-web: Stuck after login in Tor Browser: performance.mark is not a function

[ollieparanoid]

Description

I can't use the riot webapp anymore. After logging in, the spinning animation goes on forever, and the JS console says:

TypeError: performance.mark is not a function

I guess the function was disabled in Tor Browser to make fingerprinting the user harder.

Steps to reproduce

• Install Tor Browser on Linux
• Open Riot Webapp
• Login

Version information

• Platform: web (in-browser)
• Browser: Tor Browser 7.5.4 (based on Mozilla Firefox 52.8.0)
• OS: Arch Linux x86_64
• URL: https://chat.disroot.org/

Output from JS console

TypeError: asm.js type error: Disabled by 'asmjs' runtime option  olm.js

Looks like this problem would have been introduced in https://github.com/matrix-org/matrix-react-sdk/pull/1814

@t3chguy the error I am getting in https://github.com/vector-im/riot-web/issues/6809 is different. Please check the logs in the link.

my error starts like this:
TypeError: asm.js type error: Disabled by 'asmjs' runtime option olm.js
Failed to open log database: undefined bundle.js:49:9096
Failed to initialise rageshake: Error: Failed to open log database: undefined bundle.js:49:9096
InvalidStateError bundle.js:49:9674

@jadasaq no it is not, Unhandled rejection t.default<.startPageChangeTimer@https://riot.im/app/bundles/237db52ea1bc0282ffcf/bundle.js:127:16347 is from your log, startPageChangeTimer calls performance which is blocked in Tor

is that the only issue? what about the remaining errors?
also, is there any other way to signup to riot?

Ugh - @lukebarnard1 it looks like performance stuff is striking again :(

We need to be 100% certain that our performance measurement stuff doesn't break the client _ever_.

This would depend on spinning up Riot in a bunch of different browsers and doing a few tests at least before we release.

Fixed by above referenced PR.
