request: support text input with clipboard events disabled.

[gcb]

some certification bodies requires disabling clipboardEvents. I will update this later on with any doc i can share.

This can impact govt and financial institution adoption of element-web (and other clients using this SDK) as it breaks pasting to the div-as-input component here.

Not to mention usability/18n as several niche browsers/extensions/ime input do not work well with that pattern.

you can simulate cases where that feature is not available on firefox, about:config, dom.event.clipboardevents.enabled=false. copy and cut (with preventDefault at the end of the methods) works fine. Only paste is impacted currently.

I can try a patch around https://github.com/matrix-org/matrix-react-sdk/blob/develop/src/components/views/rooms/BasicMessageComposer.tsx#L357 but I am unsure about the second edge case (line 360). Someone more familiar with that would be more productive.

See #9666

@gcb worth noting that simply removing that preventDefault will most likely make the paste look like it worked but then not be in the Composer's internal data model and thus not be part of the message you send. YMMV.

This sdk is not used anywhere else?

if it's only there, i guess they prefer rich-text over all integrations that are possible using a simple text box element-hq/element-web#25544

thank you.

I guess you didn't read the README

As of Aug 2018, the only skin that exists is vector-im/element-web; it and matrix-org/matrix-react-sdk should effectively be considered as a single project (for instance, matrix-react-sdk bugs are currently filed against vector-im/element-web rather than this project).
