[WEB-1118] fix: table selections using drag handle fixed

[Palanikannan1437]

Fixes

1. Selections now occur properly, no matter the level of nesting.
2. Nesting with Tab for list items inside tables work as intended.
3. Selection works for all kinds of nodes inside tables (or any nest able node)
4. Drag behaviour fixed for tables and block-quotes without clicking on it first.

Demo (working with a list inside table inside table inside table....)

For eg, this is how GitHub supports nested tables...

	ASCII	HTML
Single backticks	'Isn't this fun?'	'Isn't this fun?'
Quotes	"Isn't this fun?"	ASCII HTML Single backticks 'Isn't this fun?' ‘Isn’t this fun?’ Quotes "Isn't this fun?" “Isn’t this fun?” Dashes -- is en-dash, --- is em-dash – is en-dash, — is em-dash
Dashes	-- is en-dash, --- is em-dash	-- is en-dash, --- is em-dash

We support it too now ;)
