Shortcuts breaking virtual keyboard functionality

[likeadeckofcards]

Description

If a user tries to enter something like 30cm^2, it causes some problems when using the virtual keyboard.

Steps to Reproduce

1. Enter 30cm using a regular keyboard
2. Open the virtual keyboard
3. Click the x^2 keycap

Actual Behavior

The latex does not update.

Expected Behavior

I would expect it to update the latex to either 30\operatorname{cm}^2 or 30\operatorname{cm^2}

Environment

Reproducible with the demo tool: https://mathlive.io/examples/latex/index.html

Operating System MacOS

Browser tested both Chrome and Firefox

Also, note that manually entering 30\operatorname{cm}^2 causes the exponent to pushed further away from the characters similar to #203.

The issue as reported is not reproducible in the main branch, however, the problem of the offset of the exponent still does (this is caused by the exponent being sometimes attached to the operator atom, sometimes to a msupsub. It should always be a msupsub)

This is now fixed in mathlive@0.0.60

I'm currently using 0.69.4 and this appears to still be an issue, including on the demo site

[arnog]

@Smef what do you mean by "the demo site"? What URL are you using?

[Smef]

The same URL as posted in the original issue posting:

https://mathlive.io/examples/latex/index.html

[arnog]

Ok, this URL was using a version of MathLive that did not have the fix,

if you’re sure you’re using the latest version and it still happens, I’ll reopen the bug and investigate. You can check the version you’re using with console.log(MathLive.version) or by importing version from the MathLive module.

[Smef]

I was incorrect and the newer packaged hadn't been properly installed. My mistake. Thanks for your attention to this issue!

[arnog]

OK, that's great to hear. Thanks for the update!
